This disease is typically spread to humans by inhalation of aerosols, or ingestion of contaminated unpasteurised milk (relatively rare). The disease has a broad host range and numerous wildlife species have been affected to varying degrees including kudu and African buffalo Syncerus caffer in southern Africa and bison and elk Cervus canadensis in Canada. The disease has also been described in wild felids, deer, elephants, rhinoceroses, hares, raccoons, bears, warthogs, primates, opossums, foxes, coyotes, mink, otters, seals, sea lions, deer, elk and some rodent species. In general the wetland manager should consider all wild mammals to be potentially susceptible to infection. Domestic species known to be susceptible include dogs, cats, pigs, ferrets, camelids, sheep, goats and horses. Although generally thought to be resistant there is little known about the susceptibility of birds to M. Geographic distribution Once found worldwide but now ‘kept at bay’ in domesticated animals in many countries due to control programmes. Eradication programmes are underway in some countries of Central and South America, the United States, Mexico, New Zealand, Japan and Europe. In cold, dark and moist conditions it can survive for several months and at 12-24°C (54-75°F), depending on the exposure to sunlight, survival time varies from 18 to 332 days. The bacterial agent may be carried on the clothing or shoes of personnel in contact with infected animals. The chief mode of transmission is exchange of respiratory secretions between infected and uninfected animals and ingestion of infected milk for calves. How does the disease Infection has been observed to spread in both directions between livestock and spread between groups wildlife, when both share the same environment and food. Potential routes of transmission include by aerosol, when in close proximity, and by ingestion when feeding in contaminated environments. In pigs, ferrets and most likely deer, ingestion seems to be the primary route of transmission. Cats may be infected via ingestion or percutaneous transmission in bites and scratches or by the respiratory route. In the case of badgers, aerosol transmission would appear to be the main route with biting being an additional possibility. Infection may also be caused by ingestion of raw or undercooked meat and through breaks in the skin. Animals may become acutely emaciated and develop severe respiratory distress in the terminal stages. In cervids, infections may be subacute or cause chronic disease with variable rates of progression. Some animals may only show abscesses of unknown origin with additional symptoms developing years later and other cases may exhibit rapid dissemination with relatively quick onset of symptoms. The most likely presentation in wildlife such as wild ungulates and carnivores (e. Recommended action if Contact and seek assistance from appropriate animal health professionals. In developed countries most infections in domestic livestock are diagnosed by routine testing or found at the slaughterhouse. A strong skin-based immune response to bovine tuberculin is consistent with infection. In many instances this is performed in a comparative manner, using avian tuberculin in addition to bovine.
