ABSTRACT
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.

A infecção por Neospora caninum é uma importante causa de abortos em bovinos, assim como mortalidade neonatal em caprinos e ovinos. Uma pesquisa sorológica de anticorpos anti-N. caninum foi realizada no município de Ibimirim (PE, Brasil). Os resultados ao teste de imunofluorescência revelaram que 26,6 por cento (85/319) dos caprinos e 64,2 por cento (52/81) dos ovinos foram positivos. A reatividade à sorologia foi associada com a idade nos caprinos (p < 0,01) e ovinos (p > 0,05), com maior ocorrência nos animais mais velhos. Estes resultados indicam exposição a N. caninum entre pequenos ruminantes na área estudada.
