Cases of zoonotic tuberculosis have been reported in Africa, the Americas, Europe, the Eastern Mediterranean, and the Western Pacific. [51] Human zoonotic tuberculosis cases are linked to the presence of bovine tuberculosis in cattle, and regions without adequate disease control measures and/or disease surveillance are at higher risk. [51]
Paratuberculosis is found worldwide, with some states in Australia (where it is usually called bovine Johne's disease or BJD) being the only areas proven to be free of the disease. [2] At least in Canada, the signs of BJD usually start when cattle are four to seven years of age, and then usually only are diagnosed in one animal at a time. [ 3 ]

Montana recorded its first confirmed case of bovine tuberculosis in more than 50 years in a beef herd in Blaine County, the state veterinarian confirmed.
The oldest unambiguously detected M. tuberculosis gives evidence of the disease in the remains of bison in Wyoming dated to around 17,000 years ago. [15] However, whether tuberculosis originated in bovines, then transferred to humans, or whether both bovine and human tuberculosis diverged from a common ancestor, remains unclear. [16]
Zoonosis or zoonotic disease can be defined as an infectious disease that can be transmitted between animals and humans. [16] One Health plays a big role in helping to prevent and control zoonotic diseases. [17] Approximately 75% of new and emerging infectious diseases in humans are defined as zoonotic. [17]
The first vaccine against smallpox by Edward Jenner in 1800 was by infection of a zoonotic bovine virus which caused a disease called cowpox. [87] Jenner had noticed that milkmaids were resistant to smallpox. Milkmaids contracted a milder version of the disease from infected cows that conferred cross immunity to the human disease.
