Bovine tuberculosis – a disease still worth fighting



DNR continues to work to eradicate bovine TB; help neededMichigan Department of Natural Resources
After more than two decades of study and testing white-tailed deer for bovine tuberculosis, Michigan has become world-renowned for its research and expertise on managing this serious contagious disease.
Over this time, Michigan Department of Natural Resources wildlife managers have learned a great deal, including that continued assistance from hunters and others remains vitally necessary to make significant gains in battling bovine tuberculosis into the future.
Tuberculosis (TB) is a serious disease caused by certain bacteria that attack the respiratory system of animals and humans.
There are several types of tuberculosis, but bovine tuberculosis (bTB) can infect the widest variety of animals and is what wildlife managers have been trying to eradicate from white-tailed deer in Michigan.
“Michigan is one of the leading experts in management and information related to bTB,” said Kelly Straka, DNR state wildlife veterinarian. “We are the only state in nation that has bTB established in wild deer.”
Although originating and typically occurring in cattle, bTB can infect nearly any mammal, including humans. Bovine TB is caused by the bacterium Mycobacterium bovis (M. bovis), which is part of the Mycobacterium tuberculosis complex. Read more
