摘要： The seroprevalence of Toxoplasma gondii infection in dairy cattle was surveyed in Jinzhou City, Northwestern China, between September and October 2011. In total, 350 serum samples were collected from 5 Holstein dairy cattle farms located in Jinzhou. Antibodies to T. gondii were found in 24 (6.86%) of 350 dairy cattle using indirect hemagglutination (IHA) test, with titers of 1:64 in 22, and 1:256 in 2 dairy cattle. Seropositive dairy cattle were found in four of five survey locations, and the seroprevalence of T. gondii infection ranged from 0 to 13.51%, but the difference was not statistically significant (P > 0.05). The correlation between seroprevalence and number of pregnancies was also analyzed, and the dairy cattle that had one birth, had the highest seroprevalence of T. gondii (12.12%), followed by dairy cattle with two and three pregnancies, 8.72 and 3.50%, respectively. However, the seroprevalence in the dairy cattle that had given one birth (12.12%) was significantly higher than that in cattle with 3 pregnancies (3.50%) (P < 0.05). The present study indicated a high seroprevalence of T. gondii in dairy cattle in Jinzhou, Northeastern China, which may cause significant economic losses to the local milk industry, and poses a potential threat to human health. Therefore, comprehensive practical control strategies and measures should be recommended to prevent and control T. gondii infection in dairy cattle in this region.
