Washington, September 16, 2014 -- The United States Department of Agricultures Animal and Plant Health Inspection Service (APHIS) has issued an interim rule upgrading the bovine tuberculosis status for seven counties in the lower peninsula of Michigan. The interim rule upgrades the status for the seven counties from Modified Accredited Advanced to Accredited Free, effectively eliminating required bovine tuberculosis testing prior to interstate movement of cattle and bison from these areas of Michigan.. APHIS has determined that the counties of Antrim, Charlevoix, Cheboygan, Crawford, Emmet, Otsego, and Presque Isle counties meet the criteria for accredited-free status. There have been no findings of bovine tuberculosis in any cattle or bison in these counties since April 2011.. Bovine tuberculosis is a contagious disease caused by bacteria that affects mainly cattle and bison. APHIS works cooperatively with state animal health officials and the livestock industry to eradicate bovine ...
TRIPP COUNTY, S.D. - Bovine tuberculosis has been confirmed in a Tripp County, S.D., beef herd.. The infected cow was identified by meat inspectors during a routine inspection in October at a Texas slaughterhouse and official records linked the cow to a Tripp County herd, according to State Veterinarian Dustin Oedekoven.. Bovine tuberculosis is a chronic respiratory disease of cattle, and infected animals can transmit the infection to other animals in close proximity.. "We are working closely with the affected herd owner, (United States Department of Agriculture) officials, area veterinarians, neighboring herd owners and wildlife officials to evaluate the extent of the disease," Oedekoven said in a press release.. Officials investigation will look to determine the source of the infection and precautions have been put in place to protect the health of the states cattle industry, Oedekoven said. ...

Tuberculin testing 20 using single comparative intradermal tuberculin test (SCITT) showed a 14.6% positive, 4% 21 doubtful and 81.4% negative reactors. Mycobacterial infection was found to be present in the 22 nomadic (constantly moving) and semi-nomadic (limited movement) management systems 23 studied but management showed no significant effect on the prevalence of the disease.

In 2002, the prevalence of bovine tuberculosis (tb) among 500 cattle on Holeta Farm, near Addis Ababa, Ethiopia, was 48 per cent, and the farm was divided into positive and negative herds. After three consecutive rounds of skin testing and segregation of skin test-positive and -negative animals, the prevalence of bovine tb was reduced from 14 per cent to 1 per cent in the negative herd in a year. Spoligotyping of 41 isolates from 17 cows gave an identical and unique spoligotype pattern, which can be represented as the binary number 1100000101111110111111100010000000000100000, where 1 indicates the presence of a spacer and 0 represents a loss. This spoligotype pattern had not previously been reported on the Mycobacterium bovis spoligotype database, and it was therefore designated sb1176, Ethiopian M bovis strain 1 (embs1). The variable number tandem repeat (vntr) profile of the strain was 5254*33.1, which differed from the vntr profile of strains reported in Great Britain.. ...
In this paper we use mathematical modelling to consider the broad advantages and disadvantages of fertility control over lethal control for bovine tuberculosis in badger populations.. We use a deliberately simple model, attempting to capture only the key transmission processes. The model is parametrized with reference to the long-term Woodchester Park study. Estimates of mortality rate from this study suggest no significant extra mortality risk for animals with evidence of infection as indicated by the presence of anti-Mycobacterium bovis antibodies or M. bovis isolation.. We find that large reductions in prevalence are sometimes the consequence of only moderate reductions in population numbers. If we assume that the act of control does not in itself affect transmission rates, then as far as eradication is concerned, both fertility control and mortality control operate through the same epidemiological mechanism, the removal of susceptibles: if one is in principle capable of keeping a population ...
Associations between specific host genes and susceptibility to Mycobacterial infections such as tuberculosis have been reported in several species. Bovine tuberculosis (bTB) impacts greatly the UK cattle industry, yet genetic predispositions have yet to be identified. We therefore used a candidate gene approach to study 384 cattle of which 160 had reacted positively to an antigenic skin test (reactors). Our approach was unusual in that it used microsatellite markers, embraced high breed diversity and focused particularly on detecting genes showing heterozygote advantage, a mode of action often overlooked in SNP-based studies. A panel of neutral markers was used to control for population substructure and using a general linear model-based approach we were also able to control for age. We found that substructure was surprisingly weak and identified two genomic regions that were strongly associated with reactor status, identified by markers INRA111 and BMS2753. In general the strength of association
Like the human version, bovine tuberculosis primarily affects the airways and the lungs of the animals and can be lethal. and the family is puzzled that cattle breeding has contracted tuberculosis and a strain previously not identified in the United States. The strain is closest to cattle-related cases in Mexico. operation, as no other cattle from Mexico were found in the area, the livestock was purchased privately rather than a larger scale for sales, and no Mexican employees were involved in the family business. Keller said this is a factor too often overlooked that people can spread tuberculosis to cattle or other animals. There are no other flocks of cattle in the Sargent district that have had direct contact. She added that animals that have a negative result can move to slaughter, but other movements are not allowed. Bovines with the disease are placed. Meat from animals undergoing inspection is safe to consume, she said. ...

[more ▼]. This assessment aimed to elaborate a statistical nationwide model for analyzing the space-time dynamics of bovine tuberculosis in search of potential risk factors that could be used to better target surveillance measures. A database comprising Mycobacterium bovis molecular profiles from all isolates obtained from Belgian outbreaks during the 1995-to-2006 period (n = 415) allowed the identification of a predominant spoligotype (SB0162). Various databases compiling 49 parameters to be tested were queried using a multiple stepwise logistic regression to assess bovine tuberculosis risk factors. Two isolate datasets were analyzed: the first included all Mycobacterium bovis isolates, while the second included only data related to ...

Several PCR systems have been developed for the detection of species belonging to the M. tuberculosis complex (MTC). The most commonly used one is based on primers that amplify segments of the IS6110 element, particularly targeting for the 123 bp (2) and 245 bp fragments (7). Another PCR system that yield successful identification of M. bovis isolates is focused on the amplification of a 500-bp DNA fragment inside the RvD1Rv2031c genomic sequence (4). A combination of conventional culture and biochemical techniques is the gold standard method currently used for the identification of M. bovis, which is laborious and time-consuming. In this study we carry out the molecular identification of pure cultures of acid-fast bacilli (AFB) isolated from suggestive bovine tuberculosis lesions. The molecular assay consists of a single-step multiplex PCR (m-PCR), based on two set primers already tested that yet to date have not been combined in a single PCR system. In this study, the assay targets ...
Bovine Tuberculosis Also known as: TB, bTB Bovine Tuberculosis (bTB) in cattle is caused by the bacterium Mycobacterium bovis. Bovine tuberculosis is a zoonotic disease and can cause tuberculosis in humans.
The overall aim of this review was to assemble the evidence that will help unravel the genetic components underlying differences in response to TB. Research in livestock host variability in response to BTB could deliver genetic markers such as SNPs associated with resistance. Implementation could be by the use of genetic markers associated with TB resistance/susceptibility in existing breeding programmes or even the identification of genetically susceptible sires to avoid their use in high BTB prevalence regions. The latter approach could help to achieve the goal set by Cox et al. (2005) who argued that even modest reduction in the reproduction number of M. bovis in cattle could bring the current epidemic under control.. It is possible that M. bovis and cattle may have reached an evolutionary stalemate, as has been proposed for humans (Muse Davis & Ramakrishnan 2009). While this proposed tolerance of host for pathogen and pathogen for host may well be an example of coevolution to maximize the ...

Thirteen goats from a TB-free herd that had no history of Johnes diseases or CLA infection were selected for the study. Six animals acted as controls and seven were experimentally infected with C pseudotuberculosis.. All goats were tested on a weekly basis for evidence of CLA lesions. Before the study, the animals were tested using single and comparative intradermal tuberculin (SIT and SCIT, respectively) tests using purified protein derivatives of Mycobacterium bovis (PPD-B) and Mycobacterium avium (PPD-A), and interferon (IFN)-γ assay for the diagnosis of TB. This testing was repeated six and 12 weeks after the experimental infection. The proportions of test reactors between the two groups was compared.. Before the test, all experimentally infected animals were negative in the SIT and SCIT tests. No difference was found in the numbers of reactors detected in the SIT and SCIT tests when comparing the control and infected groups. Two goats did react … ...

Bovine tuberculosis is a zoonotic disease with largely unknown impact in Africa, with risk factors such as HIV and direct contact with animals or consumption of Mycobacterium bovis infected animal products. In order to understand and quantify this risk and design intervention strategies, good epidemiological studies are needed. Such studies can include molecular typing of M. bovis isolates. The aim of this study was to apply these tools to provide novel information concerning the distribution of bovine tuberculosis in cattle in Mozambique and thereby provide relevant information to guide policy development and strategies to contain the disease in livestock, and reduce the risk associated with transmission to humans ...

The gamma-interferon assay (IFNγ) is often used as an ancillary diagnostic test alongside the tuberculin skin test in order to detect Mycobacterium bovis infected cattle. The performance of the IFNγ test has been evaluated in many countries worldwide and wider usage as a disease surveillance tool is constrained due to the relatively low and inconsistent specificity at a herd and area level. This results in disclosure of a higher proportion of false positive reactors when compared with the skin test. In this study, we used cohorts of animals from low prevalence tuberculosis herds (n = 136) to assess a range of risk factors that might influence the specificity of the test. Univariate and multivariate logistic generalised estimating-equation (GEE) models were used to evaluate potential risk factors associated with a false positive IFNγ test result. In these herds, the univariate model revealed that the region of herd origin, the time of year when the testing was carried out, and the age of the animal
Evaluation of the environment as a potential reservoir of M. bovis is an important step towards understanding its transmission. This study demonstrates wide variation in the prevalence of M. bovis in the environment associated with badger setts and latrines, and that the probability of molecular detection is related to the number and prevalence of badgers excreting M. bovis within the territories of social groups. The biological integrity of these results is strengthened by identification of a direct relationship between latrine positivity and social group rate of excretion of M. bovis in faeces. The failure to detect excreting badgers in six of the social groups that showed evidence of environmental M. bovis may be due to the low sensitivity of culture, variation in the probability of capturing a badger while it is excreting (Delahay et al. 2000), neighbouring excretors visiting these territories (Rogers et al. 1997) and/or M. bovis persistence following prior contamination.. To confirm the ...
General Information: This strain is a fully virulent strain that was isolated in 1997 in the UK from a cow suffering necrotic lesions in lung and bronchomediastinal lymph nodes. The strain was also reported to infect and persist in badgers that are considered to be a significant source of bovine infection. Causative agent of classic bovine tuberculosis. This genus comprises a number of Gram-positive, acid-fast, rod-shaped aerobic bacteria and is the only member of the family Mycobacteriaceae within the order Actinomycetales. Like other closely related Actinomycetales, such as Nocardia and Corynebacterium, mycobacteria have unusually high genomic DNA GC content and are capable of producing mycolic acids as major components of their cell wall. This bacterium is the causative agent of classic bovine tuberculosis, but it can also cause the disease in humans, especially if contaminated milk is consumed without prior pasteurization. The Mycobacterium bovis complex is a diverse group of species, ...

Herd health. Cattle producers need to support the health of their herd through every means possible and lower the potential exposure to all disease pathogens because one disease may impair immune response to another disease, making them more susceptible. This includes having a clean and dry environment for all cattle, particularly at calving, managing the stocking rate to keep aerosol and manure exposure lower, reducing the mixing of cattle of different ages and from different herds, and reducing the exposure of cattle to blood from other cattle. The latter may mean that you and your veterinarian commit to single use of examination sleeves and needles, and reduced use of bulls. In addition cattle should be fed diets that meet their nutritional and immune system needs including proper balancing for minerals and vitamins. Additionally, vaccination is an important tool to strengthen the immune response to certain viruses and bacteria. An animal whose health is compromised by one disease is more ...
Habitat management appears important to a farms bTB risk. Nature friendly management practices-the presence of ungrazed wildlife strips, and the greater availability, width and continuity of hedgerow-are all associated with reduced bTB incidence. The results are unlikely to be artefactual: in contrast to other habitat variables, such as deciduous woodland configuration, the boundary characteristics were retained in high-ranking models after adjustment for herd size and the proximity of the nearest infected herd. Further, the top-ranking model, which included hedgerow availability, had more than twice the support of the model containing just these non-habitat variables. Within-farm habitat characteristics were estimated with some random error in our study (because farm perimeter locations were not known), and the true relationships will therefore tend to be even stronger than those we have observed.. Any of the habitat factors associated with bTB risk locally could operate in conjunction with ...

In the 1950s, Ireland set out to eradicate bovine tuberculosis (bTB). Today, they have a very successful bTB eradication programme in place that dramatically reduced production losses, maintained their export status and has helped their beef and dairy industry flourish.
Bovine TB is one of the biggest issues facing the industry today. A devisive issue among politicians, farmers and animal welfare groups, it is one the new Government has vowed to tackle. Find out more about bovine TB, its spread and what is being done to control its spread in the UK.
The failure of the current bovine tuberculosis (TB) eradication programme could be partly due to a parasitic worm that hinders the tests used to diagnose TB in cows, according to new research published this week.
