Mycobacterium tuberculosis complex infection in Barbary sheep (Ammotragus lervia) at the Curitiba Zoo, southern Brazil¬¬: case report

Abstract

Tuberculosis is one of the most important mandatory notification diseases in the world caused by bacteria of the Mycobacterium tuberculosis complex, infecting both humans and animals. A sudden death of a Barbary sheep in Curitiba Zoo, and presence of multifocal nodules in lungs at necropsy raised suspicion of tuberculosis. Quantitative polymerase chain reaction (qPCR) from organs and fluid was performed and detected M. tuberculosis complex in a lung sample. This research reports the M. tuberculosis complex infection in Barbary sheep, a zoonosis of great relevance to public health and emphasizes the need to implement prevention measures. Furthermore, the research may provide a better understanding for species conservation, occurrence and transmission of diseases in captivity, reservoir potential and public health impact to zoo personnel and visitors.
