摘要：弓形虫病是一种重要的食源性寄生虫病。本研究于2011年5月和6月对辽宁省屠宰的猪和牛进行了刚地弓形虫血清感染调查。从5个县共采集了1164份猪血清和646份牛血清，采用间接血凝试验检测了弓形虫抗体。12.0%（140/1,164）的猪检测到弓形虫抗体，存在一定的地区差异。阜新市患病率最高，为14.4%(47/326)，锦州次之，为12.5% (62/497)；总体而言，在牛中观察到6.0%(39/646)，但没有区域差异（P < 0.05）。猪的弓形虫感染率显著高于牛（P < 0.05）。本研究结果表明，猪、牛弓形虫感染在中国包括东北辽宁省广泛传播，已引起公共卫生关注。
Abstract: Toxoplasmosis is an important food-borne parasitic disease. In the present study, the seroprevalence of Toxoplasma gondii infection in slaughtered pigs and cattle was surveyed in Liaoning Province, northeastern China in May and June 2011. In total, 1,164 porcine serum samples and 646 bovine serum samples were collected from 5 counties and examined for T. gondii antibodies by an indirect hemagglutination test. Antibodies to T. gondii were found in 12.0% (140/1,164) of pigs, with some regional differences. The highest prevalence of 14.4% (47/326) was found in Fuxin followed by 12.5% (62/497) in Jinzhou; overall, 6.0% (39/646) was observed in cattle but with no regional difference (P > 0.05). Prevalence of T. gondii infection in pigs was also significantly higher compared to cattle (P < 0.05). The results of the present study indicate that infection with T. gondii in pigs and cattle is widely spread in China including Liaoning Province, northeastern China, and is, therefore, of public health concern.
