Neospora caninum infection is an important cause of bovine abortion as well as neonatal mortality in goats and sheep. A serological survey for antibodies against N. caninum in goats and sheep was carried out in the municipality of Ibimirim, PE, Northeastern Brazil. The imunnofluoresce antibody test showed that 26.6% (85/319) of the goats and 64.2% (52/81) of the sheep were positive. Serologic reactivity was associated with age in goats (p < 0.01) and sheep (p > 0.05), with increasing rates in older animals. These results indicate exposure to N. caninum among small ruminants in the study area.
