Abstract

Neospora caninum (N. caninum) and Toxoplasma gondii (T. gondii) are both obligate intracellular protozoan parasites, which have gained considerable attention because of their role in bovine abortion. This study aimed to detect anti-N. caninum and -T. gondii in bulk milk of dairy cattle, Mashhad, Iran. The bulk milk samples were collected from July 2014 to June 2015 and analyzed for anti-N. caninum and -T.gondii antibodies using enzyme-linked immunosorbent assay (ELISA). Out of 123 bulk milk samples, 44 (35%), 14 (11.38%), and 3 (2.4%) samples had N. caninum, T. gondii, and mixed infection with these two parasites, respectively. According to the results, the prevalence of N. caninum infection was more than T.gondii infection in dairy cattle of Mashhad, Iran.

Estimation de la prévalence des anticorps dirigés contre les antigènes de Neospora caninum et Toxoplasma gondii dans le lait des réservoirs des fermes laitières dela ville de Mechhed

Abstract [French]

Neospora caninum et Toxoplasma gondii sont deux parents protozoaires intracellulaires constituant un risque sanitaire majeur en raison desavortementsqu’ils peuvent engendrés chez les vaches laitières. Cette étude avait pour objectif la détection des anticorps spécifiques aux antigènes de Neospora caninum et Toxoplasma gondii dans le laitprovenant des réservoirs des fermes laitières dans la ville de Mechhed en Iran. Pour ce faire des prélèvements de lait ont été effectués à partir desréservoirsdes fermes laitières de Mechhed entre juillet 2014 et juin 2015 et ont été soumis à un test d'ELISA afin de détecter les anticorps spécifiques aux antigènes de Neospora et de Toxoplasma. Sur un total de 123 prélèvements , 44 (35%), 14 (11,38%) et 3 (2,4%)échantillons étaient respectivement positifs au Neospora caninum, auToxoplasma gondii etaux deux espèces simultanément . Nos résultats ont révélé untaux d'infection plus important auxNeospora comparé auxToxoplasma dans les fermes laitières de la ville de Mechhed. Ces résultats ont démontré que le test ELISAsur des échantillons provenant des réservoirs de lait peut être utilisé en tant qu’un test quantitatif approprié afin d’estimer le taux dinfection auxNeospora et Toxoplasma dans les fermes laitières.
