ABSTRACT

Aim: The present cross-sectional study aimed at assessing the seroprevalence of Neospora caninum infection both at herd and within herd and at determining risk factors that are associated with its seropositivity.

Materials and Methods: A total of 90 cows distributed over seven herds located in two North-Eastern Algerian provinces were blood sampled in order to be tested for the presence of antibodies against N. caninumusing a commercially available enzyme-linked immunosorbent assay kit.

Results: The individual seroprevalence of N. caninum was found to be 12.22%, and six of the seven herds tested had at least one seropositive cow. The logistic regression model revealed that abortion (odds ratio [OR]=29.15) and parity (OR=7.38) were positively associated with the seropositivity of animals on an individual basis.

Conclusion: The study confirms the existence of N. caninum infection in cattle in North-Eastern Algeria. However, a widespread infection rate of 85.71% and its significant statistical association with previous abortion (OR=29.15) need further investigations.
