Sumario:Abstract Neospora caninum (Family: Sarcocystidae) is an obligate intracellular protozoan. It is one of the most critical abortifacients in ruminants. The seroprevalence of antibodies against N. caninum and its risk factors was investigated among 430 sheep from four North Egyptian governorates, Alexandria, Gharbia, Menofia, and Qalyubia, during the period from 2017 to 2018. Generally, the overall prevalence rate of N. caninum among sheep was 8.6%. The logistic regression analysis for the obtained data revealed that N. caninum increased significantly with age (OR = 2.4, 95% CI: 8.4–18.7) of the ewe (OR = 3.3, 95% CI: 7.6–14.9), particularly among sheep in contact with dogs (OR = 4.9, 95% CI: 7.5–14.3). Besides, locality, season, and pregnancy status of examined sheep had no significant effect on the appearance of N. caninum infection. the present findings confirm the presence of N. caninum among sheep in Egypt which probably play a role in reproductive failure in sheep. Therefore, sanitary measures and monitoring of the infection should be implemented to reduce the spreading of the infection.
