Neospora caninum infection associated with stillbirths in captive antelopes (Tragelaphus imberbis).
Neosporosis was diagnosed in full-term stillborn twin calves of captive antelopes (Tragelaphus imberbis) in a German zoo. In both calves a multifocal non-suppurative encephalitis was present and infection with Neospora (N.) caninum was confirmed by foetal serology and PCR. N. caninum-DNA was detected in brain, heart, lung, liver and spleen of a third full-term stillborn calf. Histopathological lesions were absent in this calf and antibodies against N. caninum were not detected in pleural fluid. Immunohistochemistry failed to demonstrate N. caninum antigen in all three calves.
