Pulmonary infection due to the dassie bacillus (Mycobacterium tuberculosis complex sp.) in a free-living dassie (rock hyrax-Procavia capensis) from South Africa.

摘要

We report a case of extensive necrogranulomatous pneumonia due to infection with the dassie bacillus (Mycobacterium tuberculosis complex sp.) in a free-living pregnant adult female dassie (rock hyrax-Procavia capensis). A juvenile female dassie from the same colony also showed a focal lesion in the lungs suggestive of mycobacterial pneumonia. Our findings indicate the widespread occurrence of the dassie bacillus in free-living dassies and suggest very high infection rates in some populations. The introduction of South African dassies into novel environments should be considered in this light.
