Bovine Tuberculosis (TB) is an infectious disease of cattle. It is caused by the bacterium Mycobacterium Bovis (M. Bovis) which can also infect and cause disease in many other mammals including humans, deer, goats, pigs, cats, dogs and badgers. In cattle, it is mainly a respiratory disease but clinical signs are rare. M. Bovis is most commonly found in cattle and other animals such as bison, elk, and deer. In people, M. Bovis causes TB disease that can affect the lungs, lymph nodes, and other parts of the body. Bovine TB usually affects animals such as cattle, but it can affect practically all mammals causing a general state of illness, coughing, and eventual death. It can be transmitted from animals to humans as well as to other animals.
