摘要

Neospora is one of the protozoans that can infect the male and female's reproduction system. Despite the existence of N. caninum in the genitalia, its effect on sperm characteristics was not studied yet. Therefore, the aim of this study was to investigate the influence of natural neosporosis on the sperm parameters of bulls. Using 30 bulls with neosporosis diagnosed by modified agglutination test and enzyme-linked immunosorbent assay (ELISA) and 15 healthy bulls, some sperm parameters such as sperm concentration, viability, motility, and morphology were studied and compared. Also, the activity of super oxide dismutase (SOD), glutathione peroxidase (GPX), and malondialdehyde (MDA) level as the biomarker of lipid peroxidation was investigated. Results showed that sperm concentration, viability, and motility were significantly lower in bulls with neosporosis in the present study. There were no significant differences in activities of SOD and MDA level but GPX activity was significantly increased in infected bulls.
