Occurrences of anti-Toxoplasma gondiiand anti-Neospora caninum antibodies in Barbary sheep at Curitiba zoo, southern Brazil

Barbary sheep (Ammotragus lervia) have the potential to act as hosts of important infectious diseases, particularly zoonoses. Blood samples from 17 Barbary sheep at the Curitiba zoo were collected to evaluate occurrences of anti-Toxoplasma gondii and anti-Neospora caninum antibodies, tested using the indirect immunofluorescence antibody test (IFAT). Anti-T. gondii and anti-N. caninum antibodies were detected in 4/17 (23.5%) and 4/17 (23.5%) samples, respectively. The present study has shown that Barbary sheep at Curitiba zoo were exposed to T. gondii andN. caninum and therefore may act as intermediate hosts, spreading toxoplasmosis and neosporosis within and between species in shared areas.
