مستخلص: Abortions in sheep flocks affect animal health and lead to significant losses in productivity, with severe economic consequences. In recent years, the role of protozoan parasites as the cause of ovine abortions has been significant. Here, the diagnosis of infectious causes of abortions in sheep in Israel in the last decade is reviewed, focusing on parasitic pathogens. Analysis of the serological data of sheep sera (including aborted fetuses) submitted for diagnoses between 2010 and 2019 revealed overall seroprevalence of 67.4 % and 46.7 % for Neospora spp. and Toxoplasma gondii respectively, with high rates of co-exposure (32.4 %). The seroprevalence of T. gondii was higher in aborting ewes than in pre-sale examinations (48.2 % and 28.9 %, respectively (P < 0.001)). The seroprevalence of Neospora spp. was significantly higher than the seroprevalence of Toxoplasma (P < 0.001), and was similar in samples from aborting ewes and in samples from pre-sale examinations. In addition, the presence of anti-Neospora spp. antibodies was the most prominent finding diagnosed in aborted fetuses (22.9 % of aborted fetuses, significantly higher than any other organism, P < 0.001). The results of this study demonstrate that in endemic areas the seroprevalence of N. caninum in sheep may be high, and should be considered as an important cause of abortions. However, since the seroprevalence is high even in non-aborting ewes, in order to determine the causative agent of abortion in endemic flocks, a comprehensive epidemiological investigation is warranted.
