Bovine tuberculosis bTB is an infectious disease in cattle which primarily affects the lungs.
It is thought to be transmitted within herds by inhalation of infected aerosol droplets from infected cattle. Bovine TB can affect a range of wild and domesticated mammals, including cattle, deer, pigs, and badgers. Bovine TB is caused by Mycobacterium bovis bacterium, which is closely related to the bacterium that is the most common cause of TB in people Mycobacterium tuberculosis.
Like human TB, bTB primarily affects the airways and lungs. The bTB bacteria can also infect humans and cause tuberculosis, although this is reported to be mainly through people consuming unpasteurised milk or dairy products pasteurisation kills the Mycobacterium bovis bacteria.
Infection can also occur in people who come into close enough contact with infected animals by inhaling the bacteria-containing aerosol droplets exhaled by them — but this is thought to be rare.
