Facial and genital lesions in baboons (Papio anubis) of Kibale National Park, Uganda.
We describe and document with digital images two adult male baboons (Papio anubis) from the Kibale National Park, Uganda who were infected with some kind of disease having clinical signs suggestive of Treponema pallidum. One of these males was missing his premaxilla, part of the maxilla, upper incisors, canines, and possibly the first premolars. The condition of his scrotum was not seen. The other adult male had prominent inflammation of his scrotum and, to a lesser extent, his penis. Otherwise, both males appeared normal and healthy and were apparently well integrated into the same social group. These observations suggest that an earlier report of an adult female baboon living in the same area who was missing her entire premaxilla and nose and most of her maxilla may have been suffering from a similar infection, rather than a congenital disorder, as previously speculated. If these lesions were due to T. pallidum infections, then this disease has a greater geographical distribution among non-human primates than previously known.
