Factors associated with the seroprevalence of Neospora caninum (Apicomplexa: Toxoplasmatinae) in sheep from the State of Sergipe, Brazil
The aim of this study was to determine the prevalence and factors associated with the occurrence of antibodies against Neospora caninum in sheep from Sergipe, northeastern Brazil. A total of 932 sheep serum samples from 54 properties in 19 municipalities from the State of Sergipe, Brazil were collected and assayed using an indirect fluorescent antibody test (IFAT) to assess antibodies against N. caninum. A cut-off point of 1:50 was adopted and results showed that 12.45% (116/932) of sheep were serum-reactive. Based on an unconditional logistic regression, the presence of dogs on the property was associated with protection (OR= 0.323), whereas the use of exchanged or borrowed breeding males was associated with infection (OR= 22.287). These results indicate that the occurrence of antibodies against N. caninum is endemic in the State municipalities
