Description

<p> Tuberculosis (TB) in elephants is a re-emerging disease predominantly caused by Mycobacterium tuberculosis, a human type of TB. Elephant to human TB transmission has been reported from several zoological facilities which have public health implications. Culture of respiratory samples obtained using a trunk wash procedure is regarded as the gold standard for TB diagnosis in elephants; however, this technique has many limitations. Serological methods have been developed and are widely used for TB testing in elephants in zoos around the world and elephant facilities in Asian elephant range countries. Regular TB screening of elephants and their handlers should be performed; infected elephants and handlers should be segregated and treated with anti-TB drugs according to established treatment regimens. Screening, segregation, and treatment will aid in the prevention of TB transmission between species and will contribute to the conservation of endangered wild elephants by mitigating TB spread at the captive-wild interface.</p>
