RESUMO
Abstract This study aimed to evaluate the frequency of Neospora caninum antibodies in rodents from the Island of Fernando de Noronha, Brazil, and to contribute to epidemiological data on neosporosis in this region. Blood samples were collected from 154 black-rats (Rattus rattus) and 12 rock-cavies (Kerodon rupestris). The search for anti-N. caninum antibodies was made using the NAT technique, with a cut-off of 1:20. The frequency of positive mice was 5.19% (8/154 - 1:20 titer) and all rock-cavies were negative. The low frequency of antibodies against N. caninum in rodents found in the Island shows the low contamination of the environment where these animals live.
