Serological survey of Neospora caninum in small ruminants from Pernambuco State, Brazil

Inquérito sorológico de Neospora caninum em pequenos ruminantes do estado de Pernambuco, Brasil

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.
