Prevalence of anti-Neospora caninum antibodies in Iranian goats

Many species of animals play the role of intermediate host for Neospora caninum. Although the neosporosis has a global distribution, however there is no information on goats' infection in Iran. The main goal of present study was to determine the seroprevalence of N. caninum in goats of western Iran. A total of 450 sera were taken and analyzed for antibodies to N. caninum using ELISA technique. Of those, 28 (6.2%) examined goats were found to be seropositive (95%, CI=6.2±2.2%). In which male goats (11.1%) had the highest IgG against N. caninum with more than 2 years-old (54.4%). There was significant difference between prevalence and age. Positive association were in animals with history of abortion (18/30, 60%) and IgG against N. caninum. No correlations were found between male and female. This was the first report on N. caninum infection in Iranian goats and may be responsible for abortion and economic losses in goat husbandry in the region.
