Between 7 August, 2001 and 6 October, 2001 twenty (6 females, 14 males) common squirrel monkeys (Saimiri sciureus) died at the Budapest Zoo due to toxoplasmosis and its consequences. The initial size of the colony was 57 (22 females, 35 males). The animals showed vague clinical symptoms, such as general weakness and ataxia or were found dead without prior clinical signs. The post mortem findings included acute enteritis, interstitial pneumonia, fluid in the pleural cavity, necrotic and serous hepatitis, tubulonephrosis and necrotic encephalitis. The presence of T. gondii organisms in the tissues was demonstrated by Dia-Quick staining of tissue impression smears and by immunohistochemistry in histological sections from 8 animals. Three animals died following the prolonged anti-toxoplasma therapy: two of acute gastroenteritis caused by Candida albicans and one of small intestine invagination. Toxoplasma could not be demonstrated from the later cases.
