Serological survey of anti-Leptospira spp. antibodies in Barbary sheep (Ammotragus lervia) at the Curitiba Zoo, southern Brazil

Leptospirosis is a worldwide zoonosis, affecting humans, domestic and wild animals. The present study aimed to evaluate prevalence of anti-Leptospira spp. antibodies in Barbary sheep at the Curitiba zoo. Microscopic agglutination test (MAT) was performed using 17 serogroups. Antibodies against Leptospira spp. were observed in 23.5% samples and Icterohaemorrhagiae was the only prevalent serogroup. The presence of anti-Leptospira antibodies in Barbary sheep indicates exposure to leptospires; thus monitoring and preventive measures are necessary in zoo's captive animals, since they can act as sentinels of environmental exposure in an area with high movement of people.
