Johne's Disease--Mycobacterium avium subsp. paratuberculosis: A Debilitating Enteric Disease of Ruminants
June 2002 (Revised January 2003)
Jean Larson U.S. Department of Agriculture |
There are many loses in the livestock industry as a result of the bacterial disease called Johne's disease. "The disease occurs across the US and many foreign countries and is one of the most economically important disease of cattle." 3. The effects of this contagious disease lead to reduced milk, fetal loss and early death. This disease is caused by a bacterium Mycobacterium avium sp species paratuberculosis. This family of bacteria causes a variety of disease scourges such as tuberculosis, leporsy, cervical lymphadenitis, Aswimming pool granuloma, chronic pulmonary diseases and Johne's disease. Johne's disease is known to affect cattle, sheep, llamas, camels, goats, farmed deer, bison, and other domestic and wild ruminants. It may be the cause of some wasting diseases in horses and swine. Also, chickens can be successfully infected with it. The disease can also be transmitted to laboratory animals in a laboratory setting. It may also be an agent of the Crohn=s disease in humans. There is conflicting information about the zoonotic risks of the disease, but interaction with diseased animals should be done with caution. Johne's is found world-wide.
The disease. Although the infection is usually acquired early in life, the clinical signs can take 2-6 years to develop. Clinical signs in cattle include severe wasting due to prolonged diarrhea, dehydration, and emaciation with lethal consequences. ( In other susceptible animals the clinical signs are somewhat different.) In cattle the intestinal wall becomes thickened and has transverse folds called rugae. The surface looks corrugated. Lymph nodes are also affected and at times there are lesions in the liver, spleen, lungs, kidneys. Infections in the uterus and placenta can lead to congenital infection and abortion. Most cattle are infected when young through contaminated feed, colostrum, milk, contaminated bedding and water. The organism is often shed in large number in the feces and for long periods of time. It can live for long periods in fecal material and depending on the environmental and soil conditions, has been known to survive up to 1 year.
Diagnosis. Diagnosis of the disease in live individual animals is difficult for a number of reasons. To date, "there is no single, good test for paratuberculosis and a combination of tests is often used." 1. It seems that it is easier to diagnosis the presence in a herd as apposed to individual animals. Most of the time, the definitive diagnosis is done after an animal has died. Note that in the bibliography, there is research going on to attempt to develop better diagnostic methods for this difficult disease.
Control measures. There is no satisfactory treatment for the disease. The trend toward intensive has made control more difficult. Disease control is via implementing a variety of production practices. Some of the production practices include culling of affected animals, and removal of calves from dams immediately following birth. The calves are then fed pasturized colostrum that is free of fecal contamination and raising them in a facility that is separate from adult cows. Fecal culturing of all cows in a herd can catch those affected early on. Manure removal and facility cleaning can help control the disease. Since a basic soil discourages bacterial survival in soil, liming of pastures is helpful.
Vaccines used in calfhood can be effective in reducing the incidence, but they do not totally eliminate disease. A more effective vaccine is also being researched at this time, but vaccination does not eliminate the need for good production practices.

Abstract: Transmission of Mycobacterium avium subspecies paratuberculosis,
the organism responsible for paratuberculosis (or Johne's disease) in ruminants,
occurs through the faecal-oral route. As M. a. paratuberculosis has been isolated
from rabbit faeces, cattle grazing rabbit faecal contaminated pasture may thus
be at risk. A herd of 57 beef cattle was monitored on a farm in Perthshire,
throughout the 1999 'grazing year', to investigate whether the cattle avoided
rabbit faecal contaminated pasture and thus the potential for disease transmission.
Grazing was measured every two days over eight rotations by sward heights on
40 marked treatment plots (0.5 m X 0.5 m) to which 0, 10, 50 and 250 rabbit
faecal pellets were added. Cattle were also monitored by an active transponder
system which enabled individual animals contacting two plots per field rotation
(one control and one contaminated) to be recorded. During the monitored grazing
year, grazing pressure was low with a net mean sward offtake of 18% of sward
height per rotation. There were no significant differences between rabbit faecal
treatments (0, 10, 50 and 250 pellets) with respect to the height or proportion
of sward removed, or between the numbers of contacts made by cattle on contaminated
and uncontaminated plots. Over 90% of all the cattle contacted contaminated
plots, indicating that the potential for disease transmission was widespread
among the herd. To our knowledge, this is the first reported instance of a lack
of avoidance by grazing cattle towards swards contaminated with faeces, and
implies that the potential for transmission of paratuberculosis from rabbit
contaminated pasture is high.

Abstract: Mycobacterium avium ssp. paratuberculosis (M. paratuberculosis),
the causative agent of Johne's disease, is an important animal pathogen that
has also been implicated in human disease. The major proteins expressed by M.
paratuberculosis were analyzed by two-dimensional gel electrophoresis, and a
superoxide dismutase (Sod) was identified from this protein profile. The M.
paratuberculosis Sod has a molecular mass of 23 kDa and an isoelectric point
of 6.1. Sequence analysis of the corresponding sodA gene from M. paratuberculosis
indicates that this protein is a manganese-dependent enzyme. We show that the
M. paratuberculosis Sod is actively secreted, suggesting that it may elicit
a protective cellular immune response in the host during infection.

Abstract: Attachment of Mycobacterium avium subsp. paratuberculosis to
host tissue and penetration of mucosal surfaces are pivotal events in the pathogenesis
of Johne's disease. Fibronectin (FN) binding is required for attachment and
internalization of several mycobacteria by epithelial cells in vitro. The objective
of this study was to further characterize the FN binding activity of M. avium
subsp. paratuberculosis. Although the bacteria bound FN poorly at pH above 7,
brief acid pretreatment greatly enhanced FN binding within the pH range (3 to
10) studied. A 4.6-kbp fragment from an M. avium subsp. paratuberculosis genomic
library was found to contain a 1,107-bp open reading frame that shows very high
nucleotide sequence identity with that of the FN attachment protein (FAP) gene
of M. avium subsp. avium. Pretreatment of FN with an FN-binding peptide from
M. avium subsp. avium FAP abolished FN binding, indicating that M. avium subsp.
paratuberculosis binds FN in a FAP-dependent manner. Pretreatment of M. avium
subsp. paratuberculosis with anti-FAP immunoglobulin G did not abrogate FN binding;
blocking occurred only when anti-FAP was added together with FN. FAP was detected
by immunofluorescence only in lipid-extracted M. avium subsp. paratuberculosis.
Western blotting and immunoelectron microscopy revealed that FAP is located
near the interior of the cell envelope of M. avium subsp. paratuberculosis.
The results indicate that a FAP homologue mediates the attachment of FN to M.
avium subsp. paratuberculosis. Further, given the subcellular location of FAP,
it is considered that this protein operates at the terminus of a coordinated
FN binding system in the cell envelope of M. avium subsp. paratuberculosis.

Abstract: A recent dairy survey conducted in 1996 by the National Animal
Health Monitoring System suggests between 20 and 40% of dairy herds in the United
States have some level of Johne's disease. This figure will continue to increase
unless producers implement management regimes that will help control the spread
of this disease within their herds. The neonatal calf is the target for infection
with Mycobacterium paratuberculosis, the causative agent of Johne's disease.
Calves become infected via exposure to the bacterium through contaminated feces,
bedding, colostrum, and milk. Shedding of viable M. paratuberculosis has been
documented in the colostrum and milk of infected dams. This study evaluated
the efficacy of on-farm pasteurization to destroy M. paratuberculosis in waste
milk fed to calves to circumvent this mode of transmission. In three replicate
experiments, waste milk was experimentally inoculated with M. paratuberculosis
and heated at 65.5 degrees C for 30 min. No viable bacteria were recovered after
28 wk of incubation. These results suggest that batch pasteurization of waste
milk contaminated with M. paratuberculosis was effective at generating a clean
product to feed to young calves.

Abstract: A study was conducted to determine whether trichostrongylid
nematode larvae become contaminated with Mycobacterium avium subsp. paratuberculosis
when they develop in the faeces of sheep with Johne's disease. Nematode larvae
were hatched from ova in the faecal samples of affected sheep. Larval sheaths
were removed and these as well as exsheathed larvae were subjected to radiometric
culture for M. paratuberculosis. The organism was recovered from washing water
used to prepare the larvae, third stage larvae and larval sheaths, but not from
exsheathed larvae. The recovery of M. paratuberculosis from larvae was associated
with the severity of the histological lesions in affected sheep and with the
results of culture of the organism from intestinal tissues and faeces. Nematode
parasites of sheep might be able to act as mechanical vectors for M. paratuberculosis
as the organism associates with infective third stage larvae when these develop
in the faeces of sheep with Johne's disease.

Abstract:: Since the detection of ovine Johne's disease in Australia
in 1980, 578 flocks have been diagnosed as infected, with 442 of these still
infected. The disease was initially believed to be confined to the central tablelands
area of NSW, but has subsequently been shown to be more widely distributed.
Sheep strains of M. paratuberculosis are known to infect sheep and goats in
south-eastern Australia. Although sheep strains have recently been identified
in some cattle in Australia, epidemiological evidence to date supports the distinction
between ovine Johne's disease, caused by sheep strains in sheep and goats, and
bovine Johne's disease, caused by cattle strains in cattle, goats and alpaca,
as a basis for control and eradication strategies. Four national initiatives
to control and better understand OJD are outlined. The Australian Johne's Disease
Market Assurance Program for sheep was launched in May 1997. By December 1998,
548 flocks had achieved an assessed negative status. Three flocks assigned a
flock status have subsequently been found to be infected. National standards
for State control of Johne's disease through zoning, movement controls and procedures
in infected and suspect flocks have also been developed. In addition, a $40.1
m National Ovine Johne's Disease Control and Evaluation Program was agreed to
in August 1998, and is currently being implemented. It is jointly funded by
National and State industries, and Commonwealth and State governments. Its objectives
are to deliver, through research and surveillance, a solid basis for a future
decision on the most appropriate course for dealing with OJD and to maintain
control of OJD nationally.

Abstract:: M.a. paratuberculosis is the causal agent of paratuberculosis
(Johne's disease). Recent work has suggested that gammadelta T cells may play
an important role in the early immunological response to mycobacterial diseases,
and that CD1 may act as a non-classical MHC molecule in antigen presentation
to these gammadelta T cells. Experimental infection of neonatal lambs with M.a.
paratuberculosis was used to investigate the changes in gammadelta T cells and
CD1 molecules in the gut associated lymphoid tissue 4 weeks after inoculation.
Immunohistochemistry was used to label the gammadelta lymphocytes and CD1 molecules.
An increase in the number of gammadelta T cells was noted in both the jejunal
and ileal Peyer's patches in the gut of infected lambs, but no statistically
significant change was found in the mesenteric lymph nodes. There were no obvious
changes in the CD1 molecules in any tissue. This work suggests that gammadelta
T cells may play a role in the initial immunological events of paratuberculosis
infection.

Abstract:: Organised disease control started in the Netherlands in the
18th century with governmental attempts to eradicate cattle plague. At the beginning
of the 20th century, the dairy industry and cattle breeding organisations initiated
a programme to control infectious diseases by means of a complex system of rewards
and penalties. This was also the reason for establishing the Animal Health Service
in Friesland in 1919. The history of programmes to control paratuberculosis
in sheep, goats, and cattle in various countries is described. The vaccination
of young animals seems to be an effective measure in the prevention of clinical
paratuberculosis, although changes in management and hygiene practices are also
important. A control programme for infectious cattle diseases has a number of
phases (a lifecycle) and different components. Two components are essential
for success, namely: open and regular communication with farmers, veterinary
practitioners, and other people involved and a good registration and identification
system for cattle, herds, and veterinary practitioners. The Dutch paratuberculosis
programme has 10 herd status levels: 5-10 for non-suspect herds and 1-4 for
infected herds or herds of unknown status. The higher the status, the greater
the chance that a herd is free of paratuberculosis. An outline is given of the
Dutch paratuberculosis programme including its objectives, basis principles
for eradication, communication plan, legal action, logistic considerations,
and complementary research programme.

Abstract: The national bovine paratuberculosis (PTB) seroprevalence (apparent
prevalence) in the Belgian cattle population was determined by a serological
survey that was conducted from December 1997 to March 1998. In a random sample
of herds (N = 556, 9.5%), all adult cattle of 24 months of age or older (N =
13,317, 0.4%) were tested for the presence of antibodies using a commercially
available absorbed ELISA test kit. The PTB median within-herd seroprevalence
(proportion of detected animals within the seropositive herds) and the PTB individual-animal
seroprevalence (proportion of detected animals) were, respectively, 2.9% (quartiles
= 1.6-5.6) and 0.87% (95% confidence interval (CI) = 0.71-1.03). The PTB herd
seroprevalence (proportion of detected herds) was 18% (95% CI = 14-21). Assuming
a test sensitivity and specificity of 45 and 99% [Sweeney et al., 1995. J. Vet.
Diagn. Invest. 7 (4), 488; Sockett et al., 1992. J. Clin. Microbiol. 30 (5),
1134], respectively, the median true within-herd prevalence and the true individual-animal
were estimated to be 7 and 2%, respectively. The true herd prevalence of Mycobacterium
paratuberculosis infection was first estimated according to currently accepted
methodology. This calculation revealed that the specificity of the used test
has a dramatic effect on the estimation; assuming a test sensitivity of 45%
and a true within-herd prevalence of 7%, the true herd prevalence estimation
decreased from 36 to 0.8% if the test specificity decreased from 99.9 to 99%,
respectively. This sensitivity analysis showed that the practical limits of
the accuracy of the used screening test jeopardize the estimation of the true
herd prevalence within reasonable confidence limits, because the within-herd
PTB true prevalence was low. For this reason we augmented the herd specificity
for herds with larger adult herd size (>5). This was done by increasing the
cut-off number of positive cattle required (greater than or equal to 2) to classify
a herd truly positive and including herds with one positive test result if there
was historical evidence of PTB (previous diagnosis and/or clinical signs). This
approach resulted in an estimated true herd prevalence of M. paratuberculosis
infection of 6%. The true herd prevalence for dairy, mixed and beef herds was,
respectively, 10, 11 and 3%.

Abstract:: The morphologic changes of subclinical Johne's disease in
North American Bison (Bison bison) are characterized by microgranulomas composed
of epithelioid macrophages and individual multinucleate giant cells of Langhans'-type
occasionally containing individual cytoplasmic acid-fast bacilli compatible
with Mycobacterium avium paratuberculosis. The microgranulomas are best visualized
in the mesenteric lymph nodes of infected subclinical animals. Macrophages that
can be confused with infection-associated epithelioid macrophages in the mesenteric
lymph nodes are pigment-carrying cells from the intestinal tract. Mesenteric
lymph node biopsy may be a useful diagnostic tool for detection of mild subclinical
infection in individual ruminants from herds of unknown infection status. The
biopsy may also be useful for Johne's disease surveillance during test-and-cull
programs.

Abstract:: We have recently described the GS element, found in Mycobacterium
avium subsp. paratuberculosis (MAP), Mycobacterium avium subsp. silvaticum (MAS)
and some isolates of Mycobacterium avium subsp. avium serotype 2 (MAAs2), which
contains a set of genes of low GC% content, putatively associated with the biosynthesis,
modification and transference of fucose to cell wall glycopeptidolipids. Here
we describe a further gene of low GC% content (mpa), within the GS element in
MAP. mpa is a putative acetyltransferase with homology to genes directly responsible
for host specificity and virulence in Salmonella typhimurium and Shigella flexneri.
Unlike other GS genes, strong homologues of mpa have not been found in related
species, including Mycobacterium tuberculosis (MTB). In MAP, mpa encodes an
ORF of 445aa, however, in MAS and MAAs2 mpa contains a single inserted copy
of a novel insertion sequence. This element (IS1612) has two sets of inverted
repeats at each terminus and encodes two ORFs with good homologies to transposase
and helper proteins of IS21 (E. coli) and IS1415 (R. erythropolis). Sequence
comparisons between mpa in MAP and MAS indicate the target site for IS1612 is
duplicated on insertion to give a direct repeat at each end of the element.
Immediately, downstream of the mpa gene in both MAP and MAS are a group of three
genes with good homology to the daunorubicin resistance cluster. This cluster
has a high GC% content which suggests a 'border' for the GS element. A short
motif present at the beginning of this cluster matches with an inverted repeat
of this motif at the beginning of the first gene in the GS element. This encapsulates
the whole of this group of low GC% genes in MAP and further suggests its cassette-like
nature. Homologues of the GS element in MTB show a marked similarity of organisation,
suggesting a parallel role for these genes in both pathogens.

Abstract: In order to evaluate and compare the peripheral immune responses
induced by the vaccination against paratuberculosis in relation with the age
of immunization, two groups of lambs and goat kids were vaccinated at 15 days
and 5 months old, respectively. A heat-killed commercial vaccine was inoculated
subcutaneously and humoral and cellular immune responses were measured by an
ELISA and IFN-gamma assay, respectively, at 0, 30, 90, 180, 270 and 360 dpv
in the lambs and 0, 30, 90 and 180 dpv in the caprine. IFN-gamma values did
not show statistically significant differences between both groups, but when
compared to the unvaccinated controls, this cytokine response tend to disappear
earlier in animals vaccinated at 15 days old. The antibody response was always
higher and more persistent in animals vaccinated at 5 months. The possibility
of the incomplete degree of maturation of the immune system in 15 days old animals
as the cause of the differences in the immune response to vaccination is suggested.

Abstract: As part of an ongoing Johne's disease eradication program by
the state of Victoria, Australia, the Victorian Veterinary Pathology Services
(VVPS) has been involved in testing over 150000 cattle samples per year for
the presence of Johne's-specific antibodies. The Parachek kit (CSL, Victoria,
Australia) has been used throughout the project. This method was automated using
a Rosys 3300 and a Plato 7 (Dade/Behring Diagnostics) to pipette samples and
the Behring ELISA Processor 3 (Dade/Behring Diagnostics) to wash EIA plates,
add reagents, reads absorbances and perform data reduction of the results. Automation
saved about 15 h of labour per day, allowing one staff member to analyse up
to 2000 samples per 8 h shift compared to 800 samples using a manual protocol.
Problems that were encountered include pipetting issues, the reading of the
Paracheck endpoint, and excessive packaging of the kit. Maintenance, calibration
and control of the analysers were an integral part of the process. VVPS, working
in conjunction with CSL, suggested modification to the Parachek kit to make
automation of the product more convenient. The approach resulted in a change
in reagent volume and a reduction in packaging that reduced the cost of the
test by 25%.

Abstract:: In three New South Wales dairy cattle herds with endemic Johne's
disease, prevalence rates by faecal culture were determined to be 12, 18 and
22%, respectively. Whole herd faecal culture was shown to detect markedly more
infected cattle than whole herd testing by the EMAI absorbed ELISA, particularly
in the two herds with greatest prevalence. In the three study herds, five methods
for whole herd faecal culture were compared in each. These included two methods
based on primary culture on Herrold's egg yolk medium with mycobactin J (HEYM):
(1) conventional decontamination with sedimentation and primary culture on HEYM;
(2) Whitlock decontamination and culture on HEYM. The remaining three methods
were based on radiometric (BACTEC) culture: (3) decontamination and filtration
to BACTEC medium; (4) modified Whitlock decontamination to BACTEC medium and
(5) Whitlock decontamination to BACTEC medium. For BACTEC cultures, two methods
were compared as confirmatory tests for Mycobacterium paratuberculosis: mycobactin
dependence on conventional subculture to HEYM and IS900 PCR analysis of radiometric
media. Among 179 cattle tested simultaneously by all five culture methods, 38
cattle were confirmed to be shedding M. paratuberculosis. In identifying shedder
cattle, method 5 was the most sensitive, followed by methods 2, 4, 1, and 3
was the least sensitive. The number of BACTEC cultures confirmed by mycobactin
dependence or PCR was similar.

Abstract: Paratuberculosis as well as the slow virus infections maedi/visna
and jaagsiekte came to Iceland in 1933 when 20 sheep of the Karakul breed were
imported from Halle, Germany. At least five of these sheep were subclinical
carriers of paratuberculosis. Within 16 years paratuberculosis together with
the other Karakul diseases (maedi/visna and jaagsiekte) almost ruined sheep
farming, the main agricultural industry in Iceland. The first clinical case
of paratuberculosis in sheep was confirmed in 1938, and in cattle in 1944. The
first cattle cases of paratuberculosis appeared on farms where the disease had
been prevalent in sheep for years. The virulence in cattle appeared to be considerably
lower than in sheep. Extensive measures were used to control the spread of paratuberculosis
in sheep. Hundreds of kilometres of fences were put up and used together with
natural geographic borders to restrict the movement of sheep from infected areas.
Serological and other immunological tests were also used to detect and dispose
of infected individuals. These measures proved inadequate and the disease could
not be eradicated. Culling and restocking of uninfected sheep in endemic areas
eradicated maedi/visna and jaagsiekte but not paratuberculosis. Experiments
showed that vaccination against paratuberculosis could reduce mortality in sheep
by 94%. Vaccination of sheep in endemic areas has been compulsory in Iceland
since 1966 and as a result losses have been reduced considerably. Today, serology
is used to detect and control infection in cattle herds. Furthermore, serology
is used to control vaccination of sheep and screen for infection in non-endemic
areas. The complement fixation (CF) test for paratuberculosis has been used
until now, but recently we have started comparing the CF test with the CSL absorbed
ELISA test.

Abstract:: The high sensitivity of PCR compared to the difficulties of
fecal culture in sheep prompted the development of PCR protocols for detection
of Mycobacterium avium subsp. paratuberculosis DNA in sheep feces. Although
the PCR itself is well developed, and does not pose large technical problems,
concentrating the bacteria from samples that may contain low numbers of bacilli
using practical methods is still the main difficulty for the use of this technique.
In this study, we describe an extraction protocol for the concentration and
purification of M. avium subsp. paratuberculosis DNA from fecal samples and
we compare it with other methods. The diagnostic performance of the freeze-boiling
method was evaluated using a reference method [Vet. Rec. 134 (1994) 95] on fecal
samples from a group of selected sheep from different flocks of known individual
serological, pathological, and cultural paratuberculosis status. Using, as a
reference, a combination of results in those conventional methods, the freeze-boiling
PCR protocol showed a sensitivity of 94.1%, and a specificity of 92.3%.

Abstract: Serum samples from healthy, infected (n = 11) and diseased
(n = 2) cattle as well as positive (n = 17) and negative (n = 41) reference
sera were tested for antibodies to Mycobacterium avium subsp. Paratuberculosis
with two ELISA-methods (A-ELISA, Allied Monitors, Fayette, USA; H-ELISA, Institute
of Microbiology and Animal Diseases, Veterinary University Hannover). Fecal
samples of these animals were examined by PCR and culture. Also field serum
samples found to be positive (n = 664) or inconclusive (n = 1589) by A-ELISA
during a survey done on 11028 cattle of 2757 farms at different districts in
Austria were retested with H-ELISA (Gasteiner et al., 1999). In both ELISA-methods
total agreement between antibody detection and shedding of M. avium subsp. paratuberculosis
(PCR, culture) in cases of diseased animals during the testing period was found.
In subclinically infected animals H-ELISA showed a better correlation with the
results of PCR and fecal culture. Reference serum samples of culturally negative
cattle were negative in 98% by H-ELISA and in 82% by A-ELISA, and those of positive
animals were positive in 59% by H-ELISA and in 82% by A-ELISA. The 664 A-ELISA
positive field serum samples were positive in 20.5%, inconclusive in 32.5% and
negative in 47% by H-ELISA. A-ELISA inconclusive sera gave positive reactions
by H-ELISA in 5.2%, negative in 74.8% and inconclusive results in 20%. The highest
prevalence of antibodies (7.9% by A- and 2.2% by H-ELISA) against M. avium subsp.
paratuberculosis were found in cattle at the age of six and seven years. Seropositive
animals were found at all tested ages. The A-ELISA gave two to three times more
positive reactors than the H-ELISA. Also both, tests showed the highest prevalence
of reagents among Holstein Friesian (6.2% by A-ELISA, 2.5% by H-ELISA) followed
by other cattle breeds. Seropositive cattle were observed in all districts of
Austria in 3.3-7.1% and in 0.5-1.8% of herds according to A- and H-ELISA, respectively.

Abstract: Milk and faeces samples from cows with clinical symptoms of
paratuberculosis were examined for the presence of Mycobacterium avium subsp.
paratuberculosis (M. paratuberculosis) by culture and PCR. M. paratuberculosis
was cultivated in variable numbers from faeces or intestinal mucosa in eight
of 11 animals. In milk from five cows (all faeces culture positive), we cultivated
a few colonies of M. paratuberculosis (<100 CFU per ml). Milk samples from
two cows were PCR positive (both animals were faeces culture positive, and one
cow was milk culture positive). One cow was culture negative on intestinal mucosa,
but culture positive in milk, and two cows were negative in culture and PCR
from both faeces and milk. In conclusion, the presence of M. paratuberculosis
could be detected in raw milk by PCR, but cultivation of milk was more sensitive.

Abstract:: In a deer farm, chronic diarrhoea was seen in a 4-year-old
hind. This animal died in poor condition on the farm and Johne's disease was
suspected. Ziehl-Neelsen staining of the faeces of this hind were positive for
the presence of clumps of small acid-fast bacilli, but faecal cultures remained
negative. Direct and indirect tests were performed on 24 hinds and stags (yearlings,
2- and 4-year-old animals). The indirect tests performed were serology (Mycobacterium
paratuberculosis antibody ELISA, HerdChek, Idexx), comparative cervical skin
test (CCT) and lymphoproliferation test (LT) using Mycobacterium bovis purified
protein derivative (PPD) and Mycobacterium avium PPD as antigens. Three positive
serological results, three positive CCT and eight positive LT were observed
in hinds and stags older than 2 years. No positive serological results were
observed in the yearling group, whereas some sensitisation was observed in the
CCT as well as in the LT for the same group of animals. The degree of concordance
between these indirect tests was poor. The three seropositive animals were slaughtered
and subjected to post-mortem examination. Histopathology was performed on mesenteric
lymph nodes and on the terminal ileum. Visual changes in some mesenteric lymph
nodes were observed, no gross lesion was seen in the intestine. Although Ziehl-Neelsen
staining yielded no positive results, a catarrhal focal necrotic enteritis associated
with a granulomatous lymphadenitis compatible with Johne's disease was evidenced.
The mycobacterial cultures on organ samples from slaughtered animals were positive
after 2 months for M. avium subspecies paratuberculosis and negative for M.
bovis and M. avium. This is the first description of Johne's disease in a deer
farm in Belgium.

Abstract:: The potential use of a novel immunomagnetic PCR (IMS-PCR)
technique as a rapid method to screen milk samples for the presence of Mycobacterium
avium subsp. paratuberculosis (M. ptb) was assessed. Immunomagnetic separation
(IMS) for M. ptb, developed at Queen's University, Belfast, was applied to milk
samples prior to IS900 PCR in order to selectively concentrate any M. ptb cells
present and, at the same time, separate the cells from constituents of milk
likely to inhibit subsequent PCR. This increased the sensitivity of IS900 PCR.
IMS-PCR sensitivity could be further increased by initial centrifugation (2500
g for 20 min) of larger volumes of milk (10 and 50 ml), and resuspension of
the sediment into a 1 ml volume appropriate for IMS treatment. Following IMS,
template DNA for IS900 PCR was obtained by heating the bead-cell suspension
in a thermal cycler at 100 degrees C for 15 min. It was estimated that the IMS-PCR
assay could detect approximately 10(3) CFU of M. ptb per 50 ml of milk (equivalent
to 20 CFU/ml), whereas the minimum detection limit of direct IS900 PCR was estimated
at 10(5) CFU of M. ptb per 50 ml (equivalent to 2000 CFU/ml). A blind trial
was carried out in which a total of 40 spiked (10(6) CFU M. ptb) and unspiked,
raw and laboratory-pasteurised milk samples were independently tested by IMS-PCR
and conventional IS900 PCR. IMS-PCR correctly identified 97.5% of milk samples
(sensitivity 100%, specificity 95%), including spiked milk samples before and
after laboratory-pasteurisation. One false positive result was obtained which
may have resulted from carryover between samples during the IMS procedure. Conventional
IS900 PCR correctly identified only 72.5% of the same 40 milk samples (sensitivity
23%, specificity 100%). IMS-PCR was also shown to be capable of detecting natural
M. ptb infection in raw sheep's milk, and raw and commercially pasteurised cows'
milk.

Abstract:: Cell wall deficient forms of mycobacteria may be important
in the pathogenesis of Crohn's disease and sarcoidosis. However, no method has
been available to localize this type of organisms in tissue sections. We developed
an in situ hybridization method for the demonstration of Mycobacterium paratuberculosis
spheroplasts (cell wall deficient forms) in paraffin embedded tissue sections.
M. paratuberculosis spheroplasts were prepared by treatment with glycine and
lysozyme. Pieces of beef were injected with the prepared spheroplasts. The samples
were fixed in buffered formalin and paraffin embedded. A M. paratuberculosis-specific
probe derived from the IS900 gene was used. Specificity was controlled by using
an irrelevant probe and by hybridizing sections with spheroplasts from other
bacteria. Beef samples injected with M. paratuberculosis spheroplasts were the
only samples that hybridized with the probe. Beef samples containing acid-fast
or spheroplast forms of M. smegmatis and M. tuberculosis as well as the acid-fast
forms of M. paratuberculosis did not hybridize with the probe. Unrelated bacterial
controls, i.e. Helicobacter pylori and Escherichia coli were also negative in
the assay. In situ hybridization with the IS900 probe provides a specific way
to localize M. paratuberculosis spheroplasts in tissue sections and may be useful
for studies of the connection between M. paratuberculosis and Crohn's disease
and sarcoidosis. The assay may also be valuable for studies on Johne's diseased
animals.

Abstract:: In 1996, the cattle industries and government in the Australian
state of Victoria established a Johne's disease (JD) test and control program
under which participating farmers are provided with an annual ELISA test of
their adult herd and advice on disease control that is tailored to their farm.
The program is delivered through private veterinarians under contract with the
government. There are over 600 herds enrolled in the program and about one third
of these have had three or more whole herd tests. This paper provides a review
of the program to date. It describes changes in ELISA reactor rates and numbers
of clinical cases, and provides evidence for progress in the program.

Abstract:: Cattle strains of Mycobacterium paratuberculosis are known
to infect cattle, goats and alpaca in southeastern Australia, where there are
also significant numbers of farmed deer. Although sheep strains have recently
been identified in some cattle in Australia, epidemiological evidence to date
supports the distinction (between bovine Johne's disease (JD), caused by cattle
strains in cattle, goats and alpaca, and ovine JD, caused by sheep strains in
sheep and goats) for the purposes of control and assurance programs. The National
Johne's Disease Control Program is coordinated by the Australian Animal Health
Council, working with the livestock industries and with the Commonwealth, state
and territory governments. The council also brokers industry and government
funding for the program. The National Johne's Disease Market Assurance Program
for Cattle was launched in 1996 as the first of a suite of voluntary national
market assurance programs (MAPs) to assess and certify herds as negative for
JD. By December 1998, over 550 herds had achieved an assessed negative status.
A MAP was also launched for alpaca in 1998 and a program for goats should be
finalised in early 1999. National standards for state control of JD through
zoning, movement controls and procedures in infected and suspect herds have
also been developed. The paper covers factors affecting development and implementation,
uptake of and improvements to national control and assurance programs for bovine
JD in Australia.

Abstract:: Pathogenesis studies of Mycobacterium avium subsp. paratuberculosis
infection in ruminants are hampered by the long incubation time of the disease.
A laboratory animal model with a shorter incubation time would facilitate research
in this field. Although small rodents are usually considered to be resistant
to M.a. paratuberculosis infection, several susceptible murine strains have
been found. To our knowledge, there are no detailed reports with regard to susceptibility
in rats. The Lewis rat is a valuable model for inflammatory bowel disease studies
as well as autoimmune diseases involving mycobacteria as inducing agents. In
this study Lewis rats were used to investigate their potential as a small laboratory
animal model for paratuberculosis. In total 28 female Lewis rats were orally
inoculated with M.a. paratuberculosis. The rats were first inoculated at 3 weeks
of age, and 12 more inoculations followed in increasing intervals during the
3 months to follow. Eight control rats received a sham inoculation. Over 9 months,
two rats from each group were sacrificed at regular intervals and immunological
and histopathological examinations were performed on the gastrointestinal tract,
the liver and the spleen. None of the rats developed lesions which were indicative
of mycobacterial infection as determined by histology with HE and Ziehl-Neelsen
staining. The bacteria could not be recultured from samples taken from the gut,
the liver or the spleen. The immunological tests however, showed that bacteria
had entered via the intestinal tract. From this study it appears that Lewis
rats are resistant to oral inoculation with M.a. paratuberculosis, and not suitable
as a model to study the immunopathogenesis ofparatuberculosis as it occurs in
ruminants.

Abstract:: Mycobacterium avium subsp. paratuberculosis infection, or
Johne's disease, reportedly has a low prevalence in South American camelid populations.
Recently, however, single cases in the United States as well as an outbreak
of the disease in Australian alpacas (Lama pacos) have been described. To provide
a rapid and cost-effective method of diagnosing Johne's disease in this species,
the bovine Parachek Johne's Absorbed EIA (CSL, Vic., Australia) was modified
to create a camelid-specific serum antibody assay. An anti-llama IgG conjugated
to horseradish peroxidase replaced the anti-bovine immunoglobulin. Checkerboard
titration of principal reagents was performed using serum from nine tissue and/or
fecal culture-positive camelids. Optimal dilutions of key components were determined
in order to provide clear discrimination between positive and negative controls.
Completion of a kinetic assay determined the optical density at which the enzyme-substrate
reaction should be stopped. A herd of 100 camelids with no history of disease
or exposure to M. a. paratuberculosis, a subset of which were tissue and/or
fecal culture-negative, was tested to establish a cut-off value. Sample results
were expressed as a percentage of the results for control sera by transforming
optical density values to ELISA values (EV%). A preliminary EV% cut-off of 20
was established. Using this prototype assay, culture-positive animals showed
significantly different antibody responses from culture-negative animals. These
results indicate that this camelid-specific ELISA, once refined, may be a useful
tool for screening camelid herds for M. a. paratuberculosis infection.

Abstract:: During a serological survey for ovine paratuberculosis a total
of 145934 ovine serum samples from 2019 farms throughout South Africa were tested
by means of the AGID assay. Fifty-two infected farms were identified in the
Western Cape and Eastern Cape provinces. Links between infected farms in the
two provinces were established. Examination of the distribution of infected
farms in the Western Cape indicated a positive correlation between acid soils
and occurrence of infection. In an attempt to increase the sensitivity and facilitate
screening of large numbers of sera two commercial ELISA systems were evaluated
for their potential use in a future monitoring program. Sera from histologically
positive sheep and known negative sheep flocks were used. The highest sensitivity
(50.9%) was found if both ELISA systems were run concurrently and the results
of both systems combined.

Abstract:: In the Netherlands a survey was conducted to estimate the
prevalence of paratuberculosis in dairy herds. In total 15822 cows of at least
3 years of age, belonging to 378 herds were tested using an absorbed ELISA.
Of these herds, 55% (n = 207) had one or more serologically positive cows. Of
the positive non-vaccinated herds, most had one (n = 98) or two (n = 49) positive
cows. The percentage positive cows per herd was 2.5 +/- 3.2%. The true prevalences
on cow and herd levels, based on a test sensitivity that ranged from 0.3 to
0.4 and a specificity that ranged from 0.985 and 0.995, were estimated at 2.7-6.9%
and 31-71%. Seven herds had been vaccinated against paratuberculosis and these
herds had a significantly higher percentage of serologically positive cows (23%)
than the non-vaccinated herds (2.5%). In conclusion, a small percentage of the
dairy cows and a high percentage of the dairy herds in the Netherlands is serologically
positive. The percentages true infected cows and herds are difficult to estimate
precisely due to uncertainties in test sensitivity and specificity.

Abstract:Crohn's disease (CD) is a chronic inflammatory bowel disease
that is similar to Johne's disease in ruminants. Recent data have strengthened
the association of M. avium subsp. paratuberculosis (M. paratuberculosis) with
CD. To provide more evidence of an etiological association, antibody reactivities
from CD patients were tested by immunoblotting against recombinant antigens
that were identified previously from our M. paratuberculosis genomic library.
Two clones (designated pMptb#40 (3.2-kb insert) and #48 (1.4-kb insert) expressing
a 35K (p35)- and 36K (p36)-antigens showed specific reactivities with serum
samples from CD patients. Serum samples from 75% of 53 CD patients, 14% of 35
normal individuals and 10% of 10 ulcerative colitis patients reacted to p35
antigen. Reactivities were also observed with serum samples from 89% of 89 CD
patients, 14% of 50 normal controls and 15% of 29 ulcerative colitis patients
reacted with p36 antigen. When the reactivity results from p35 and p36 were
combined, the background from the controls was eliminated, i.e. only the CD
patients reacted to both p35 and p36. The positive predictive value was 98%
with specificity of 98% and the negative predictive value was 76% with sensitivity
of 74% (39 positive out of 53). A statistical significance (p < 0.0001) was
observed when the results from CD serum samples reacting with either or both
antigens were compared to the controls. The reactivity of anti-M. paratuberculosis
(specifically against p35 and p36 antigens) antibodies in a significant proportion
of CD patients would suggest a causal role for the organism in CD.

Abstract:: In two studies carried out during the period 1995-1998, paratuberculosis
was diagnosed in domestic and wild ruminants in the Czech Republic. The isolated
Mycobacterium avium subspecies paratuberculosis strains were analysed by standardised
restriction fragment length polymorphism (RFLP) [Pavlik, I., Horvathova, A.,
Dvorska, L., Bartl, J., Svastova, P., du Maine, R., Rychlik, I., 1999. J. Microbiol.
Methods 38, 155-167]. In December 1992, 19 late pregnant Charolais heifers were
imported to the Czech Republic from Hungary (original import from France to
Hungary). One 11-month-old heifer roamed in the wild in a range of approximately
15-20 km for 7 months from November 1993 to May 1994. Upon capture, the animal
showed clinical signs of paratuberculosis (emaciation and diarrhoea). Seven
other animals from the same herd were infected with the identical RFLP type
B-C1 of M. paratuberculosis. During the period 1995-1996, samples were taken
and examined from the small intestine and corresponding lymph nodes of 84 wild
ruminants: 19 red deers (Cervus elaphus) and 65 roe-deers (Capreolus capreolus).
These wild ruminants originated from 44 different locations within the same
district from as the infected escaped heifer. Five M. paratuberculosis strains
were isolated: one strain of RFLP type B-C1 from a stag and three strains of
RFLP type B-C1 and one strain of RFLP type B-C9 from roe-deer. The three wild
ruminants (one stag and two roe-deer) infected with the same RFLP type B-C1
were detected in the same area as the heifer, suggesting that this was the likely
infection source. However, the infection source of the roe-deer infected with
strain of RFLP type B-C9 was obviously different, and the stags that escaped
from the farm were purchased from an area infected with this RFLP type. In the
second study carried out during 1997-1998 in the whole Czech Republic (divided
into 76 districts), 718 wild ruminants were examined from 90% of the districts.
M. paratuberculosis was isolated from 25 (3.5%) animals from the wild, from
farms and from game parks: 7.1% of 132 red deers, 1.5% of 336 roe-deers, 3.9%
of 178 fallow deers (Dama dama), and 4.2% of 48 moufflons (Ovis musimon). This
study discovered three RFLP types (B-C1, D-C12 and M-C16). A surprising finding
was that of M. paratuberculosis (RFLP type B-C1) infection in roe-deer and a
fallow deer in their natural habitat. The infection source was determined to
have originated from two imported Holstein and Limousine cattle herds infected
with the same strain. In the case of a mother and daughter roe-deer infected
with RFLP type M-C16 and a fallow deer infected with RFLP type D-C12, all roaming
in their natural habitat, the infection source was not discovered. The highest
incidence of clinically ill wild ruminants was found in farmed red deer, and
no relationship was found between the RFLP type or ruminant species and clinical
status of animal.

Abstract:: Faecal (at least 3 months before slaughtering) and organ examinations
were carried out in 611 animals (497 dairy, 69 dual-purpose and 44 beef cattle)
originating from eight paratuberculosis infected cattle herds. The diagnosis
in cattle was established by routine intestinal culture (ileum and the adjacent
lymph nodes) after slaughter. In selected 132 animals, post-mortem intensive
culture was performed on tissue samples collected from the gastrointestinal
tract (duodenum, jejunum, ileum, ileocecal valve, caecum, rectum) and the corresponding
lymph nodes, submandibular, retropharyngeal, tracheobronchial, liver and supramammary
lymph nodes, kidney, liver and spleen. In 251 (41.1%) of all 611 animals, Mycobacterium
avium subspecies paratuberculosis could be isolated from the faeces; in 164
(65.7%) out of 251 shedding animals the infection was detected in the ileum
and adjacent lymph nodes. The detection of M. paratuberculosis by routine intestinal
culture of faecal culture positive animals varied from 46.0% in animals shedding
1 CFU (colony forming unit), to 94.7% in massive shedders. On the contrary,
M. paratuberculosis was detected by routine intestinal culture in 92 (25.5%)
of the 360 faecal culture negative animals. Shedding animals had significantly
higher (P < 0.01) number of organisms in their organs than non-shedding animals.
During the intensive tissue cultivation from selected 132 animals, 72 (54.5%)
of them were positive. For the negative animals, no significant difference was
found between the detection rate in organs examined after slaughter with routine
and intensive method. However, in the subgroup of tissue culture positive animals
a highly significant difference (P < 0.01) was found by intensive examination
(83.0%) compared with the routine examination (60.4%). Out of 72 tissue culture
positive animals 73.6% of them harboured M. paratuberculosis in the gastrointestinal
tract, 16.7% in the gastrointestinal tract and the parenchymatous organs, tracheobronchial
and mandibular lymph nodes. The rest of the 9.7% of the infection was detected
in the lymph nodes of head and lungs. Our study concerning the distribution
of M. paratuberculosis by intensive examinations revealed a minimum effect of
breed and production type on localisation of the agent. Thus, the results suggest
that in case of an active infection, M. paratuberculosis can be localised in
different organs of animals irrespective of their breed or production type.

Abstract:: Crohn's disease is a chronic, relapsing inflammatory condition
affecting any part of the human gastrointestinal tract. It is characterized
by transmural inflammation with deep ulceration, thickening of the bowel wall
and fistula formation. The hallmark is the non-caseating granuloma. Clinical
presentation depends upon the site of the inflammation. Pain and diarrhoea are
frequent. Extraintestinal manifestations develop in up to 25% of patients and
perianal disease is also frequent. The aetiology of Crohn's disease remains
unknown. On the host side, genetic factors are important and the immune system
is central to the development of the inflammation. Several environmental factors
also play a role, in particular smoking. The presence of intestinal luminal
contents appears to be essential for the development of Crohn's disease. A number
of specific infectious causes have also been proposed, most recently measles
virus and M. avium subsp. Paratuberculosis. The latter has been considered because
of the similarity between BJD and Crohn's disease, although there are also important
differences. Evidence suggesting that this agent plays a role includes isolation
of the organism from some patients, clustering, and identification by PCR of
M.a. paratuberculosis DNA in tissue. However, many other workers have been unable
to reproduce these findings. Treatment of Crohn's disease is generally with
5-aminosalicylic acid (5-ASA) compounds, corticosteroids, immunosuppressive
agents and antibiotics. The majority of patients with active disease will respond
to one or a combination of the therapies. Recently, broad-spectrum antibiotics
have been shown to be as effective as oral corticosteroids. The challenge in
Crohn's disease remains the prevention of relapse once remission has been achieved.
Oral 5-ASA preparations can be beneficial, particularly after surgery. Immunosuppression,
particularly with azathioprine or 6-mercaptopurine, is helpful in patients with
resistant inflammation. Antibiotics may delay the time to relapse when used
for active disease. The use of antimycobacterial therapy directed against M.a.
paratuberculosis shows promising results but needs further evaluation. Up to
80% of patients with Crohn's disease will require surgery at some stage in the
course of their illness. The challenge remains to try and prevent resection
of inflamed intestine and to improve the quality of life of those affected by
this disorder.

Abstract:: Mycobacterium paratuberculosis, an acid-fast bacillus that
causes enteritis in ruminants, has been suggested as an etiological agent of
Crohn's disease in humans. The mode of transmission is unclear; however, some
evidence suggests that humans may become infected via contaminated milk. Currently,
it is not known whether commercial pasteurization effectively kills M. paratuberculosis
in contaminated raw milk. Using a laboratory-scale pasteurizer unit designed
to simulate the high-temperature, short-time method (72 degrees C, 15 sec) currently
used by commercial dairies, we previously demonstrated that treatment of raw
milk inoculated with 10(4) to 10(6) cfu of M. paratuberculosis/ml reduced numbers
to an undetectable level. However, M. paratuberculosis is an intracellular pathogen
that resides within the macrophages of the host and evades destruction. We subsequently
performed further experiments examining heat treatment of milk inoculated with
mammary gland macrophages containing ingested M. paratuberculosis. Heat treatment
of these samples under high-temperature, short-time conditions demonstrated
that the macrophage does not protect the organism because we were unable to
recover any viable M. paratuberculosis from the samples. Conversely, other researchers
have demonstrated that a residual population of M. paratuberculosis may survive
heat treatment of milk. In addition, a recent news report stated that viable
M. paratuberculosis organisms have been cultured from retail-ready milk in Ireland.
A summary of past and current studies concerning this issue along with a discussion
of methodologies used to recover M. paratuberculosis from experimentally inoculated
milk will be presented in this paper.

Abstract:: The host immune response to infection with Mycobacterium paratuberculosis
is paradoxical, with strong cell-mediated immune responses during the early,
subclinical stages of infection and strong humoral responses during the late
clinical stages of the disease. Cell-mediated immune responses modulated by
various T cell subsets are essential to provide protective immunity and prevent
progression of the disease. Secretion of cytokines by T cell populations serves
to activate macrophages to kill ingested M. paratuberculosis as well as activate
other T cell subsets to contain the infection. This paper reviews the current
knowledge of T cell immune responses in M. paratuberculosis infection based
upon clinical studies and research using mouse models.

Abstract:: The sensitivity and specificity of the ELISA and fecal culture
tests for paratuberculosis in dairy cattle are examined. ELISA and fecal culture
data from seven dairy herds where both fecal cultures and ELISA testing was
done concurrently are included. A cohort of 954 cattle including 697 parturient
adults, cultured every 6 months from 10 herds followed over 4 years served as
the basis to determine fecal culture sensitivity. The fecal culture technique
utilized a 2 g sample with centrifugation and double incubation. Of the 954
cattle cohort of all ages (calf to adult) that were fecal sampled on the first
herd visit, 79 were culture positive. An additional 131 animals were detected
as culture positive over the next seven tests at 6-month intervals. The sensitivity
of fecal culture to detect infected cattle on the first sampling was 38%. Of
the 697 parturient cattle cohort, 67 were positive on the first fecal culture,
while an additional 91 adult cattle were culture positive over the next seven
tests, resulting in a sensitivity of 42% on the first culture of the total animals
identified as culture positive. Animals culled from the herds prior to being
detected as infected and animals always fecal culture negative with culture
positive tissues at slaughter are not included in the calculations. Both groups
of infected cattle will lower the apparent sensitivity of fecal culture. Infected
dairy herds tested concurrently with both fecal culture and ELISA usually resulted
in more than twofold positive animals by culture compared to ELISA. The classification
of infected cattle by the extent of shedding of Mycobacterium paratuberculosis
in the feces helps define the relative proportion of cattle in each group and
therefore the likelihood of detection by the ELISA test. ELISA has a higher
sensitivity in animals with a heavier bacterial load, i.e. high shedders (75%)
compared to low shedders (15%). Repeated testing of infected herds identifies
a higher proportion of low shedders which are more likely to be ELISA negative.
Thus, the sensitivity of the ELISA test decreases with repeated herd testing
over time, since heavy shedders will be culled first from the herds.

Abstract:: Questionnaires were posted to 800 randomly selected registered
Victorian dairy farmers in 1996. Five hundred and thirty-four responses were
received and analysed. Johne's disease (JD) had been diagnosed on the farm of
13.2% of respondents in the last 5 years. JD was rated second only to neonatal
diarrhoea in importance as a disease of calves, even though other diseases occurred
more frequently. However, there was a low level of compliance with JD control
recommendations by the respondents. There was no significant difference in the
number of JD control recommendations adopted by farmers between the three major
Victorian regions. There was a significant difference in compliance between
farms having had a diagnosed case of JD and those that had not. Although there
is awareness among dairy farmers of the importance of JD, there appears to be
a poor implementation of measures by farmers to prevent the spread of the disease.
Current JD control recommendations and the method of information transfer to
Victorian dairy farms should be reassessed to ensure that dairy heifers are
reared with minimal risk of transmission of JD.

Abstract: The invention relates to a nucleotide sequence which is present
at a position adjacent to the 5' end of the reverse sequence complementary to
the open reading frame coding for a potential transposase contained in the insertion
element IS900 in Mycobacterium paratuberculosis. The nucleotide sequence has
promoter functions and contains important signals for the regulation of transcription
and translation. The invention also relates to methods for cloning and expressing
heterologous proteins using such regulatory sequences, to vectors and transformed
host cells containing these sequences, and to immunogenic compositions prepared
by expression of nucleotide sequences placed under control of these regulatory
sequences.

SUBJECT: The use
of micro-colony pcr for detection of Mycobacterium paratuberculosis from bovine
manure.
OBJECTIVES: Our objective
is to assess and optimize the PCR confirmation of M. paratuberculosis
microcolonies. The primary hypothesis to be tested is that PCR analysis can be
performed on micocolonies of M. paratuberculosis appearing between 7-14 days
afer spirally plated on Middlebrook agar plates. The use of PCR on
micro-colonies will circumvent the problems of sensitivity and PCR inhibition
when this technique is used directly on broth cultures, manure or tissues.
APPROACH: Bovine manure
from clinically normal cows will first be spiked with up to 1x10(8) CFU/g of M.
paratuberculosis and decontaminated via the standard protocol used by the
California Animal Health Food Safety Laboratory (CAHFS, Davis CA). After the
decontamination step, teh samples will be spirally plated onto Middlebrooks
7H10 agar plates for micro-colony morphology detection. The spiral plates will
be incubated at 37 degrees centigrade and examined weekly for M.
paratuberculosis growth. The resulting micro-colonies will be "picked"
from the spiral plates and the DNA extracted from them. PCR amplification using
an automated LightCycler and M. paratuberculosis specific primers will then be
performed with results of a typical 30cycle reaction obtainable within 30
minutes. Primer concentration, MgCl concentration, annealing temperatures and
cycle numbers will all be assessed and adjusted for maximum sensitivity and
specificity.
NON-TECHNICAL SUMMARY:
Detection of M. paratuberculosis in young cattle continues to be difficult
using current tests. In an effort to improve the sensitivity and specificity of
PCR for Johne's disease screen assays, we plan to investigate a micro-colony
PCR detection method.

Prophylactic vaccine against Mycobacterium paratuberculosis in cattle.
OBJECTIVES:
Johne's disease, a chronic granulomatous enteritis of cattle is the result of
infection with the extremely slow growing bacillus Mycobacterium
paratuberculosis. It is estimated that 20-30% of US dairy and cattle herds are
infected with this organism with resulting combined losses to the dairy and
beef industries estimated to be between $200 million and $1 billion per year.
Current vaccine strategies utilizing non-viable mycobacteria have proven to be
largely ineffective and are currently permitted in only 3 states. We further
hypothesize, based on our extensive experience with murine models of
mycobacteria infection, that successful vaccines must incorporate proteins
contained within the Culture Filtrate (CFP) extracted from the supernatant of
mycobacteria during the log phase of growth. We propose here to vaccinate
several small groups of cattle with mixtures of M. paratuberculosis CFP
emulsified into adjuvants which have been demonstrated to promote a T helper
Type I (THI) immune response: experimentally infect these animals via oral
inoculation with a clinical isolate of M. paratuberculosis: and to monitor
these animals for the emergence of T cell populations previously associated
with protection. Animals will be analyzed for DTH response, T cell production
of IFN-g, and circulating memory T cell phenotype expression.
APPROACH:
See Objectives.

SUMMARY: We anticipate that a combination of M. paratuberculosis CFP emulsified
into a TH1-promoting adjuvant will stimulate a protective T cell response in
experimentally infected cattle. This response will be characterized by an
emerging, circulating T cell population which produces significant amounts of
IFN-y in response to in vitro exposure to CFP and exhibits a shift towards a

Defining
novel diagnostic and vaccine targets to combat Johnes disease.
OBJECTIVES:
To define new antigenic proteins of Mycobacterium paratuberculosis which can be
used as diagnostic markers and vaccine candidates for the purpose of
eliminating this pathogen from cattle. This mycobacterium is the etiological
agent of Johnes disease, a common disease in cattle. We will isolate and
characterize mycobacterial protein antigens which elicit a B cell and T cell
response in M. paratuberculosis infected cattle and test these antigens as
potential vaccine candidates using a mouse M. paratuberculosis infection model.
APPROACH:
To use PCR and genetic library screening to clone Mycobacterium
paratuberculosis genes which we hypothesize to be immunogenic in infected
cattle. The cloned genes will be expressed as recombinant proteins and tested
as diagnostic markers for Johnes diseased cattle. Specifically, serum from
infected and control cattle will be tested for antibodies to the recombinant
proteins by Western blot. We will also measure the T cell proliferative
response to these proteins using T cells isolated from infected and control
cattle and the ability of the isolated T cells to produce cytokines in response
to these recombinant proteins. To determine if these proteins would make useful
vaccine candidates, mice will be immunized with one or more of these antigens
and then challenged with M. paratuberculosis. A decrease in bacterial load at
different times post-infection would indicate a protective response intitiated
by the immunization. Additional diagnostic markers and vaccine candidates will
be defined by screening a M. paratuberculosis expression library with serum
from infected cattle. The recombinant proteins within the expression library
which show reactivity with antibodies from infected cattle will be purified and
tested in the T cell proliferation and cytokine production assays as described
above and as vaccine candidates.
NON-TECHNICAL
SUMMARY: Johnes disease is a chronic intestinal disorder particularly common
among dairy cattle and it is estimated that 24% of the dairy herds nationally
are infected. By some estimates the cost of Johnes disease to dairy farmers
exceeds 1.5 billion a year. This disease is caused by Mycobacterium
paratuberculosis, an intracellular pathogen, whose other family members include
M. tuberculosis and M. leprae, the causative agents of tuberculosis and leprosy
respectively. Infected cattle shed high numbers of M. paratuberculosis through
their feces where it can spread to other members of the herd. A major interest
to dairy farmers is the development of diagnostic tools and vaccines for Johnes
disease. However, we lack the required information on what M. paratuberculosis
proteins initiate an immune response in infected cattle and which of these
proteins, when used as a vaccine, would protect the calf or cow from Johnes
disease. Nevertheless, studies with other pathogenic mycobacteria have identified
proteins which produce an immune response in infected animals, including
humans. Further, a number of these proteins were shown to protect an animal
host from an active mycobacterial disease when used as a vaccine. We have
chosen to clone the M. paratuberculosis genes corresponding to these homologous
proteins which include GroES, fibronectin attachment protein (FAP), 85abc and
the 16-KDa a-crystallin homolog. The proteins corresponding to these genes will
be expressed and tested as diagnostic markers to distinguish M.
paratuberculosis infected from non-infected cattle. The proteins will also

SUBJECT: Immunomagnetic separation assay for
Mycobacterium paratuberculosis.
OBJECTIVES:
Johne's disease, caused by Mycobacterium paratuberculosis (M. para), is a
chronic inflamatory bowel disease of ruminants. Recent literature has fueled an
as-yet unresolved debate about whether this organism is also the etiological
agent of at least some proportion of Crohn's Disease in humans. Detection of
the organism in stool is difficult due to the slow growth and fastidious nature
of M. para. hampering many of the studies of its pathogenesis and interfering
with eradication efforts in cattle. PCR-based detection of M para is highly
specific, due to the presence of a unique sequence (IS900), but extensive
sample preparation and PCR inhibitors in stool limit the sensitivity and
utility of the method.
APPROACH:
See Objectives.
NON-TECHNICAL
SUMMARY: Current testing for M. paratuberculosis in stool samples requires
extensive sample preparation, including disinfection steps that reduce the
sensitivity of culture. PCR testing of stool samples is hampered by inhibitors
of the reaction present in stool. The proposed IMS sample preparation method
would provide increased sample throughput as well as enhanced sensitivity of
detection by replacing the harsh sample preparation steps with a gentle, immune
capture step to isolate the bacteria prior to culture or PCR.

Effect of pasteurizing waste milk on health and performance in dairy calves
with emphasis on Johne's disease and salmonellosis.
OBJECTIVES:
1. Describe, in a laboratory setting, the effect of pasteurization on
survivability and concentration of Mycobacterium paratuberculosis in whole milk
samples artifically inoculated with known concentrations of bacteria. 2.
Describe the effect of pasteurization on survivability and concentration of
Mycobacterium paratuberculosis in naturally infected waste milk when using an
on-farm pasteurization system. 3. Describe the effect of pasteurization of
waste milk on morbidity, mortality and treatment rates in calves from birth to
three months of age. 4. Describe the effect of pasteurization of waste milk on
rate of gain in calves from birth to three months of age. 5. Calculate the
economics (cost-benefit) of using an on-farm pasteurization system for feeding
pasteurized, as compared to systems feeding raw waste milk or systems feeding
commercial milk replacer.
APPROACH:
Stage 1: Laboratory Study: A commercial continuous-flow high temperature short
residence time (HTST) pasteurizer will be set up in a laboratory setting. A
series of previously commercially pasteurized samples of whole milk will be inoculated
with various concentrations of a number of different pathogenic bacteria
including M. paratuberculosis. The inoculated milk will be processed through
the pasteurizer, which involves heating to 162 degrees F for 15 to 20 seconds.
Initial innoculum levels achieved and the number of pathogenic cells surviving
heat treatment will be estimated using the appropriate culturing techniques for
each pathogen. The information acquired from this study will provide a basis
for the farm study. Stage 2: Farm Study: A commercial continuous-flow HTST
pasteurization system will be installed on a large dairy farm or heifer grower
operation. Immediately after birth, heifer calves will be fed four liters of
colostrum from a Johne's ELISA test-negative dam, weighed, placed into an
individual calf hutche, and then randomly assigned to either a treatment or
control group. Calves in the control group will receive unpasteurized waste
milk until weaning. Calves in the treatment group will receive pasteurized
waste milk until weaning (eight weeks of age). Information collected for dams
will include identification, calving date, parity, calf sex, and calf
identification number. Farm personnel will collect and freeze colostrum samples
from cows at the time of calving, and separate pre- and post-pasteurized
samples of pooled waste milk twice/week. Farm personnel will record all disease
events, treatment regimes, and mortality events for study calves up to three
months of age. Appropriate samples will be submitted to the Minnesota Veterinary
Diagnostic Laboratory to identify causes of morbidity and mortality in study
calves. Blood and fecal samples will be collected weekly from all recently
calved cows that recently delivered female calves to test for infection with M.
paratuberculosis. Fecal samples will be collected from pre-weaned calves for
the purpose of culture for detection of shedding of M. paratuberculosis. All
health and treatment records will also be collected. Finally, all study calves
will be weighed at approximately one, two and three months of age. Data will be
analyzed to describe the efficacy of pasteurization on viability of M.
Paratuberculosis in both artificially inoculated milk (laboratory setting) and
naturally infected milk (farm setting). We will compare the rate of fecal
shedding of M. paratuberculosis, and morbidity, mortality, treatment and growth
rates, in calves fed pooled pasteurized waste milk as compared to calves fed
raw waste milk. Finally, we will construct a partial budget (cost-benefit)
analysis of using an on-farm pasteurization system for feeding pooled
pasteurized waste milk, as compared to systems feeding raw waste milk or
commercial milk replacer.
NON-TECHNICAL
SUMMARY: A) The feeding of raw waste milk to calves is one important method of
transmitting Mycobacterium paratuberculosis, the agent causing Johne's disease,
as well as other infectious agents which cause diarrhea, pneumonia, septicemia
and other common calfhood diseases. The purpose of this study is to investigate
the efficacy, practicality and cost-effectiveness of implementing a
pasteurization system on a commercial dairy farm.

Critical components of host immune response in Johne's disease.
OBJECTIVES:
To determine the capacity of M. paratuberculosis-infected calves to mount a
specific cellular immune response.
APPROACH:
Our working hypothesis is that susceptibility of calves to persistent M.
paratuberculosis-infection results from inherent differences in the capacity of
macrophages to present antigen to the immune system or of immune cells to
respond to antigens presented by macrophages. We will use an in vivo model in
which calves will be infected with M. paratuberculosis organisms. We will
sequentially monitor immune responses occurring over 6 months and evaluate the
role of CD-4+, CD-8+, and gamma delta T-lymphocytes in the immune response.

SUMMARY: Johne's disease, which is caused by infection with Mycobacterium avium

presently a cause of major economic losses to farmers. This project examines
cellular immune mechanisms that determine whether cattle eliminate the

The
Penn State FY 1999 Milk Safety Research Program.
OBJECTIVES:
The FY 1999 application for Special Research Grant funds in Milk Safety
consists of three collaborative projects whose teams include S. J. Knabel, R.
Ananthaswaran, B. Jayarao and S. Pillai (Project #1), C. Deb Roy, C. Maddox, R.
Roberts and T. Whittam (Project #2), and R. J. Warland and R. O. Hermann
(Project #3), respectively. Project #1 will test the destruction of Gram-positive
microbes during high-temperature-short time (HTST) pasteurization of milk. Two
foodborne pathogens (Listeria monocytogenes and Mycobacterium
paratuberculosis), both of potentially large health and economic impact, will
be quantified in raw milk samples collected on Pennsylvania farms and after
transport to the dairy or cooperative. The objectives include to determine (1)
the effect of sublethal heat shock on the destruction of M. paratuberculosis
during HTST pasteurization of milk; (2) the effect of sublethal heat shock on
the destruction of L. monocytogenes during HTST pasteurization of milk. It is
not known whether the current pasteurization processes completely destroy these
pathogens. This information is expected to be used to design commercial HTST
pasteurization processes for producers, to improve milk safety and dairy
profitability. Project #2 will investigate the presence of enterohemorrhagic E.
coli (EHEC), such as E. coli type O157:H7, in bulk-tank milk collected on
Pennsylvania farms. EHEC are the cause of a serious disease syndrome in humans.
Therefore information on the presence or absence of EHEC is of particular
interest to producers. Although EHEC will be destroyed by proper pasteurization
of milk, the prevalence of this pathogen in raw bulk tank milk is not known. If
these strains are prevalent and may survive the manufacture process of certain
cheeses or yogurts, then clearly it will be necessary to develop methods to
eliminate them. Tests of the ability of EHEC to withstand environmental
stresses, such as acidic and alkaline conditions, will be conducted. Treatment
with colicins, known antimicrobial compounds, may provide one approach to
destroying this pathogen. The objectives include to (1) determine the serotype
and EHEC strains in raw milk collected in different geographical regions in
Pennsylvania; (2) type the virulence factors by polymerase-chain reaction
(PCR), using a battery of primers for a total of 14 virulence genes; (3) assess
the ability of EHEC to withstand the challenges of the external environment;
(4) investigate the ability of known colicins (of which 24 are available) to
control the growth of EHEC strains in milk products. Project #3 will test the
feasibility of determining consumer concerns using a standardized phone survey
instruments to assess perceptions of the safety of milk, to provide the
industry with accurate, detailed information on the beliefs of consumers
related to milk and milk product (cheese) safety. The identification of
consumers most likely to be concerned could help to focus future educational
efforts more effectively.
APPROACH:
Project #1: Use an emersed coil apparatus for HTST treatment to test the
thermal inactivation of microorganisms at HTST pasteurization conditions. Plate
cultures on special media and determine colony growth for L. monocytogenes and
M. paratuberculosis. Conduct data analysis (decimal reduction times) and
statistical comparisons of treatments. Project #2: Identify EHEC strains by
specialized cultures; determine "O" and "H" serotypes and
presence of shiga-like toxins. Determine virulence factors using DNA
amplification by multiplex PCR and ribotyping. Assess the ability of EHEC
strains to withstand challenges of environment by exposure to acidic and
alkaline conditions; determine under growth and starvation conditions. Evaluate
temperature and salt challenges. Examine sensitivity to 24 colicins using an
overlay plating technique and Pearce Activity tests; conduct pilot tests of
ColE2-producing transformants under Cheddar cheese manufacture conditions.
Project #3: Construct a pre-test survey instrument with questions based on
survey questions previously developed by the investigators and new questions
related to milk and cheese consumption to provide important information about concerns
related to dairy product-related hazards. Conduct a national survey of 2000
telephone respondents 18 years old or older (2.2% confidence). Use computer
assisted telephone survey software to analyze data. Oversample less educated
consumers to increase the probability of including adequate numbers in the
national telephone survey. Conduct various regression tests to analyze data.

SUMMARY: Milk Safety research to be conducted in FY 1999 at the Pennsylvania
State University will evaluate new pasteurization methods, use molecular assays
to test for pathogenic E. Coli in milk, and determine consumer concerns related
to the safety of the milk supply and milk products. The first project will test
the destruction by high-temperature-short time (HTST) pasteurization of
foodborne pathogens (Listeria monocytogenes and Mycobacterium paratuberculosis)
in raw milk. Data will be collected from samples on the farm and during
transport to the dairy to answer the question whether the current pasteurization
processes completely destroy these pathogens. Other research will employ
molecular methods to investigate the presence of enterohemolytic E. coli (EHEC)
in bulk tank milk. Information on the presence or absence of EHEC would be of
interest to producers as a means of detection that could be used to certify
herds. The use of colicin (an antibacterial agent) to eliminate EHEC in food
will also be tested. A third project will utilize survey methods to determine
consumer concerns about milk safety, in order to provide the dairy industry
with accurate detailed information on beliefs related to milk and milk product
(cheese) safety. The identification of consumers most likely to be concerned
could help to focus educational efforts effectively. Together, these three
projects will provide important new information to help reduce microbiological
hazards in milk and milk products, and to understand consumer concerns so that
education can be appropriately targeted.
PROGRESS:
1999/09 TO 2001/09 Milk & milk products have been linked with outbreaks
involving contamination with deadly pathogen, E. coli. We examined the presence
of pathogenic E. coli strains, such as E. coli O157 or any Shiga-like toxin
producing E. coli (STEC) that are known to be human pathogens, in raw milk. To
determine if the consumers in PA drinking raw milk are at risk, we chose to
work with raw milk from 4 dairy farms in PA including an Amish farm. Raw milk
was collected and tested for the presence of pathogenic E. coli strains.
Diagnosis of pathogenic strains of E. coli from raw milk is complicated by the
low number of the pathogenic bacteria in total bacterial counts in raw milk. E.
coli present in the milk had to be enriched in selective media to even detect
their presence. Rainbow agar and MacConkey Sorbitol agar were used to culture
bulk tank (BT) milk with high coliform counts. Other methods were also used to
enrich E. coli in BT milk such as enriching the bacteria in Rainbow or Sorbitol
MacConkey agar before these colonies were picked. Other media were also
examined for enriching the STEC. Total number of raw milk tested in 1 yr was
383. Out of these cultures 93 cultures were found to exhibit growth in the
selective media for STEC strains. These were screened for the presence of
virulence factors by Polymerase Chain Reaction (PCR). The genes that were
tested were Shiga toxin I (stx-I), Shiga toxin-II (stx-II), attaching and
effacing gene (eae) and some of the isolates were also tested for hemolysin
(hlyA). The presence of Intimin alleles (Int allele) were determined by
multiplex PCR. Thirteen isolates were found to carry virulence factors. Shiga
toxin genes were present in 10 isolates. The other 3 isolates carried either
hemolysin or attaching and effacing gene. Three isolates carried both Shiga toxin
genes I and II. There were 4 isolates with beta- Intimin which is
characteristic of O157:H7 and its close relatives (O157:NM, O55:H7). The 3 O111
strains exhibited the presence of eae but carried a distinct allele that
differs in sequence from the others. The most common pathogenic group of E.
coli recovered in this sample are members of EHEC 2, enterohemorrhagic E. coli
(EHEC) that typically have beta-Intimin and stx 1 genes. Strains of this group
are often recovered from animal sources and cause enteric diseases in calves.
Two other EHEC are also found in the sample. The O157:H7 fits the typical
formula for the O157:H7 clone that is common in N. America; positive for
gamma-Intimin and carrying both stx genes. We evaluated the survival L.
monocytogenes and M. avium subsp. paratuberculosis in milk using the HTST
protocol. The assay was done using an Immersed coil apparatus. We found the
survival rate of heat shocked L. monocytogenes pasteurized at 71.7 degrees C to
be 10/10, 7/10, & 1/10 at 15s, 20s & 25s, respectively. About 10 `6'
cfu/ml of M. paratuberculosis (with & without heat shock treatment) was
subjected to HTST protocol. The survival rate of M. paratuberculosis varied
considerably; however, a large % of the samples survived the pasteurization process.
The findings suggest that failure in HTST systems could pose a health hazard.
IMPACT:
1999/09 TO 2001/09 Microbial food safety is an increasing public health concern
worldwide. It is estimated that each year in the US there are approximately 76
million food borne illnesses. Nearly 270,000 cases are caused by pathogenic E.
coli strains including E. coli O157:H7. Although E. coli usually cause mild to
moderate self limiting gastroenteritis, invasive diseases and complications may
occur resulting in more severe cases of bloody diarrhea and hemolytic uremic
syndrome. While it is known that contaminated raw or undercooked red meat are
particularly important in transmitting food-borne E. coli, not much is known
about the contamination in raw milk. Since a large population in PA drinks raw
milk, investigation was conducted to determine whether the population is at
risk of food poisoning because of the presence of pathogenic E. coli strains in
raw milk. E. coli was isolated from raw milk and molecular characterization
reflected that some of these isolates carried genes that encoded virulence
attributes. The results of our study indicated that pathogenic E. coli strains
are indeed present in raw milk. It is therefore, suggested that raw milk should
be avoided so that pathogenic strains are not consumed. Consumers of raw milk
should be informed of the risk of food poisoning by education and extension
services.

SUBJECT:
Johne's disease in cattle and buffalo (bison): A South Dakota concern.
OBJECTIVES:
1. Develop a sensitive, rapid, high-throughput, molecular diagnostic polymerase
chain reaction (PCR) technique for the detection and quantitation of
Mycobacterium paratuberculosis in dairy and beef cattle, buffalo and products
such as colostrum and milk for human consumption. 2. Describe the distribution
and quantity of Mycobacterium paratuberculosis in young cattle, which are the
primary subclinical carriers of the organism, to identify the tissue site or
secretion which most consistently and reliably could be used for Johne's
Disease diagnosis.
APPROACH:
Diagnosis of Johne's Disease is difficult since the organism may be shed
intermittently in feces and may take 16 weeks to grow in culture. Also, serology
may detect less than half the infected animals, since antibodies develop late
after infection. Recently, voluntary Johne's Certification Programs have been
established using the antibody test in combination with culturing of the
organism to attempt eradication of this disease. However, due to poor test
sensitivity and prolonged culturing time, this is difficult. As an alternative
to culturing the organism or detecting antibodies to M. paratuberculosis, PCR
tests which can detect very small amounts of the organisms DNA have been
developed. We are currently using a PCR test for the detection Johne's Disease.
However, the conventional PCR tests are very laborious, not easily used for
quantitation and only a small number of samples can be tested at one time. An
automated, rapid, high-throughput PCR test using fluorescent probes called
molecular beacons may provide a better diagnostic test. A 96-well plate can be
used allowing for more samples to be tested at one time. Also, the system is
automated using computer software for fluorescent detection and is not as labor
intensive. The ''bacterial load' or quantity can also be evaluated, providing
information on which tissue site or secretion contains the highest numbers of
bacteria. This would provide information on which specimen would be most useful
for submission to the diagnostic laboratory for the detection of the organism.
It would also identify animals, which may be shedding large numbers of the
bacteria, allowing for better culling decisions. To evaluate this automated PCR
procedure, the sensitivity and specificity of the test will be obtained by
comparisons with culturing which is considered the gold standard. A study
involving 3-week old calves will be performed since these are the primary
subclinical carriers of the disease. The calves will be inoculated with M.
paratuberculosis, then serum, white blood cells, feces and tissue specimens
will be collected and evaluated. This study will determine which specimen
contains the highest numbers of M. paratuberculosis and would be the most
valuable for submissions for organism identification. Fourteen to 18 month old
beef calves will also be evaluated at slaughter. Tissues from these beef calves
will be collected and compared to antibody test levels in the herd to determine
whether slaughter check testing may be more valuable in the Johne's-free
certification program than antibody testing. A third study evaluating fecal
specimens from a Johne's positive buffalo herd will be obtained to determine
the usefulness of an automated, quantitative PCR procedure in diagnosing
Johne's Disease carriers in buffalo. Finally, milk and colostrum samples from a
private company in South Dakota will be evaluated by automated PCR to determine
the best method of extracting M. paratuberculosis DNA from milk and colostrum
and whether automated PCR can be used to screen milk samples for M.
paratuberculosis before and after commercial pasteurization.
NON-TECHNICAL
SUMMARY: Diagnosis of Johne's disease is difficult since current serology,
culture and PCR techniques are not adequate in identifying subclinical
carriers. We propose to develop a sensitive, rapid, high-throughput PCR for
detection and quantitation of Mycobacterium paratuberculosis in cattle, buffalo
and colostrum and milk products for human consumption and describe the
pathogenesis in young cattle.
PROGRESS:
2001/01 TO 2001/12 Johne's Disease is a chronic wasting disease of ruminants
caused by the bacteria Mycobacterium avium subsp. paratuberculosis. Traditional
diagnostic methods currently include culture of feces and tissues for the
detection of the bacteria and enzyme-linked immunosorbent assays for antibody
detection. Since conventional culturing involves a long incubation time (12-16
weeks) and antibodies may not be detectable until late in infection,
alternative methods of diagnosis are needed. We recently developed an automated
PCR assay using fluorescent probes called molecular beacons. This PCR test was
evaluated using 41 bovine fecal samples from the 1999 and 2000 National
Veterinary Services Laboratory Proficiency Testing Program. The DNA extraction
was performed directly from bovine feces and the PCR was performed in a 96-well
plate format on an ABI PRISM 7700 Sequence Detection System. Only 1 of 41
samples was negative by the automated PCR but positive by culture. This sample
had low numbers of colony forming units (CFU) (eg. 9-12 CFU). One of 41samples
was positive by PCR whereas culture was negative. It is possible this sample
may have had bacterial DNA as detected by PCR, but not viable bacteria. The
intra and inter-assay variability was also determined as a coefficient of
variation of < 2% and < 4%, respectively. Results were quantitated using
a standard curve derived from a plasmid containing IS900, with a minimum quantity
of 1.7 x 10 -4 pg of DNA being detected, which correlated to 1 to 8 CFU. The
automated PCR is currently being used for on-going studies of the pathogenesis
of Mycobacterium paratuberculosis in newborn calves and in comparisons of
bacterial detection in colostrum, feces and whole blood samples. Additional
samples from bison will also be evaluated for the presence and quantitation of
Mycobacterium paratuberculosis.
IMPACT:
2001/01 TO 2001/12 Since Johne's cerification programs are being instituted
nationally, a rapid method of detecting Mycobacteriuim paratuberculosis
infected animals is needed. The real-time PCR methodology allows for multiple
samples to be evaluated and quantitated in a 96-well plate format for detection
and pathogenesis studies.
