TB is airborne and spreads through tiny droplets in the air. Symptoms of TB: chronic weight loss, diminished appetite, chronic nasal discharge, coughing, and intolerance to exercise, and unnormal volumes of drinking water.

Between 1994 and 2006, there have been 36 culture-confirmed cases of tuberculosis in U.S. elephants, most of them asian elephants (Report of the Committee on Tuberculosis, Elephant TB Diagnostics and Guidelines by Michele Mille).

Elephant Tuberculosis (by Susan Mikota)
Definition. Tuberculosis (TB) is an infectious bacterial disease affecting numerous Species. TB occurs in primates, elephants, rhinoceroses, tapirs, domestic and nondomestic bovidae, other nondomestic ungulates, and psittacine birds.

TB has been known to occur in elephants for over 2000 years.127 Reports from the 19th and early 20th centuries25,6,50,84,207,286 described the disease in Asian elephants. The first report of TB in African elephants was in 1962. 95,96 Additional reports appeared in the middle of the 20th century.100,107,133,229,254,267 In 1994 TB “emerged” as a disease of concern for captive elephants in North America, and between 1994 and 2005, 34 cases were confirmed (Mikota, unpublished). TB has also been reported in elephants in Europe.

Tuberculosis (TB) is a re-emerging infectious disease that can be transmitted within and between humans and animal Species by transfer of mycobacteria of the Mycobacterium tuberculosis complex (MTBC). Its main representatives are M. tuberculosis (1), particularly infecting humans, and M. bovis hosted by a broad range of domestic and wild animals, as well as humans. Infection of captive and wild Asian elephants (Elephas maximus) with M. tuberculosis has been shown worldwide (4–7). Transmission of M. tuberculosis from humans to elephants as well as other Species and vice versa, is likely to happen in situations of close and prolonged contact and may occur via air, droplets, mucus and feces (1, 4, 6, 8–12). Transmission between domesticated and wild elephants may furthermore occur in direct contact at their interface (6, 13–15) and, because mycobacteria can survive for more than 45 days in the environment, shared facilities and resources may be major risk factors for infection with M. tuberculosis. Especially in countries in South East Asia, like Thailand where TB prevalence in humans is very high, zoo employees, including ground keepers and custodians show a high incidence of interferon gamma release assay or tuberculin skin test positivity, indicating (latent) infection, related to their socio-economic background, thus identifying them as potential risk factors for the animals in their care.
