Bovine Tuberculosis (TB) is caused by Mycobacterium bovis: an organism closely related to the organism that causes avian TB (Mycobacterium avian), human TB (Mycobacterium tuberculosis), and Johne’s disease (Mycobacterium avian subspecies paratuberculosis). While bovine TB can affect any warm-blooded mammal, infection of nonruminants is comparatively rare. Transmission of TB usually involves inhalation of bacteria as aerosols exhaled by infected animals, so close contact is required. However, contaminated feed, milk, pastures and water are other routes of transmission.
