Reducing The Public Health Impact Of Bovine Tuberculosis By Controlling Disease Transmission Between Cattle And White-Tailed Deer In Northwestern Minnesota, Barbara Knust
Michigan Bovine Tuberculosis Bibliography and Database
Bovine tuberculosis, caused by infection with Mycobacterium bovis, is a re-emerging zoonotic disease. It has staged a comeback by establishing infections in wildlife and cattle, creating the potential for human disease in locations where it was thought to be under control. In northwestern Minnesota, infected cattle and white-tailed deer were first discovered in 2005. A major bovine tuberculosis eradication campaign is underway in the state, with multiple efforts employed to control M. bovis infection in both cattle and deer populations. In order to effectively eradicate bovine tuberculosis in Minnesota, there is a need for better understanding of the factors …

Captive and free-ranging wildlife animals are implicated in the maintenance and transmission of bovine tuberculosis and therefore pose a significant obstacle to eradication of the disease from domestic livestock. The current antemortem diagnostic method, the intradermal tuberculin skin test, is impractical for routine use with many wild animals. Antibody-based assays are particularly attractive because the animals are handled only once and immediate processing of the sample is not required. This report characterizes the antibody responses of red deer-elk hybrids (Cervus elaphus) against Mycobacterium bovis and subsequently evaluates the diagnostic performance of select antigens in a rapid-test format. Sequential …

Assessment Of Risk Associated With The Minnesota Proposed Plan For Split-State Status For Mycobacterium Bovis (Bovine Tuberculosis)
Michigan Bovine Tuberculosis Bibliography and Database
In July 2005, a Minnesota beef herd tested positive for Mycobacterium bovis (M. bovis) and was officially declared infected with bovine tuberculosis (TB). This was the first infected herd identified since Minnesota’s Accredited Free (AF) status was obtained in 1976. Subsequent testing identified infection in white-tailed deer and several cattle herds adjacent to this index herd. In February 2008, Minnesota declared its 11th infected cattle herd, resulting in the downgrade of the entire State’s TB status to Modified Accredited (MA).
In an effort to minimize the impact of MA status to the State and producers, Minnesota initiated the …

Michigan Bovine Tuberculosis Eradication Project: 2008 Activities Report
Michigan Bovine Tuberculosis Bibliography and Database
Bovine Tuberculosis (TB) is an infectious disease that is close to being eradicated in the United States, but still poses a significant risk to domestic livestock, wildlife, companion animals, and humans throughout the world. The Michigan Bovine TB Eradication Project involves a multiagency team of experts from the Michigan Departments of Agriculture, Natural Resources and Community Health, Michigan State University, and the US Department of Agriculture.

Managing Bovine Tuberculosis In White-Tailed Deer In Northwestern Minnesota: A 2008 Progress Report, Michelle Carstensen, Erika Butler, Michael Doncarlos, Lou Cornicelli
Michigan Bovine Tuberculosis Bibliography and Database
Bovine tuberculosis (TB), first discovered in 2005, has now been found in 12 cattle operations in northwestern Minnesota. To date, all of the infected cattle herds have been depopulated and the Board of Animal Health (BAH) has continued to test cattle herds in the area. The strain has been identified as one that is consistent with Bovine TB found in cattle in the southwestern United States and Mexico. In response to the disease being detected in cattle, the Minnesota Department of Natural Resources (MNDNR) began surveillance efforts in free-ranging white-tailed deer (Odocoileus virginianus) within a 15-mile radius of …

Michigan Bovine Tuberculosis Bibliography and Database
Bovine tuberculosis (TB) is endemic in white-tailed deer (Odocoileus virginianus) in the northeastern portion of Michigan’s Lower Peninsula. Bovine TB in deer and cattle has created immense fi nancial consequences for the livestock industry and hunting public. Surveillance identified coyotes (Canis latrans) as potential bio-accumulators of Mycobacterium bovis, a finding that generated interest in their potential to serve as sentinels for monitoring disease risk. We sampled 175 coyotes in the bovine TB–endemic area. Fifty-eight tested positive, and infection prevalence by county ranged from 19% to 52% (statistical mean 33%, SE 0.07). By contrast, prevalence in …

Risks Associated With The Transmission Of Bovine Tuberculosis From White-Tailed Deer To Cattle In Michigan: Current Research, Are R. Berentsen, Mike R. Dunbar, Regina Ebersole, Robert G. Mclean
Michigan Bovine Tuberculosis Bibliography and Database
Bovine tuberculosis (bTB) is a contagious disease of livestock, wildlife, and humans. Typically, it is transmitted through inhalation of aerosolized bacilli and direct or indirect contact between animals. In northeastern Michigan, bTB is endemic in white-tailed deer, and evidence suggests deer have spread the disease to domestic cattle. Previous research indicates bTB transmission likely occurs through contamination of cattle feeding sources by infected deer and subsequent use by cattle. We are investigating deer movements in relation to farm management practices such as feeding schedules as well as locations of cattle feeding areas, hay storage sites, barns, and water sources. All …

Mitogen- and antigen-induced interferon-γ (IFN-γ) responses of peripheral blood leucocytes from cervids were evaluated by a commercial whole-blood assay. The assay was applied to Mycobacterium bovis-infected white-tailed deer and reindeer, M bovis BCG-vaccinated white-tailed deer and elk, and unvaccinated, uninfected white-tailed deer, fallow deer, elk and reindeer. The responses of the M bovis-infected white-tailed deer to pokeweed mitogen (PWM) varied with time and between individuals. The responses of the M bovis-infected reindeer to PWM and M bovis purified protein derivative (PPD) were positively associated. Samples from tuberculosis-free captive herds in various parts of the USA were also …

Numerous species of mammals are susceptible to Mycobacterium bovis, the causative agent of bovine tuberculosis (TB). Several wildlife hosts have emerged as reservoirs of M. bovis infection for domestic livestock in different countries. In the present study, blood samples were collected from Eurasian badgers (n = 1532), white-tailed deer (n = 463), brushtail possums (n = 129), and wild boar (n = 177) for evaluation of antibody responses to M. bovis infection by a lateral-flow rapid test (RT) and multiantigen print immunoassay (MAPIA). Magnitude of the antibody responses and antigen recognition patterns varied among the animals as determined by …
