In the present study, a total of 1,235 porcine serum samples were collected from 9 counties in Jilin Province (40°52'46°18'N,121°38'131°19'E), northeastern China from August to October 2013, and the seroprevalence of Toxoplasma gondii infection was tested by indirect haemagglutination assay (IHA). The results showed that antibodies to T. gondii were found in 19.1% (95% confidence interval [CI], 16.9% to 21.3%), with higher seroprevalence in the breeding boars (28.6%, 95% CI, 20.0% to 37.2%), and breeding sows (32.0%, 95% CI, 25.2% to 38.9%). No significant difference was found among the slaughter pigs, fattening pigs and the piglets. These results indicated that infection with T. gondii in pigs is widespread in Jilin province, and is of public health concern.
在本研究中，于2013年8月至10月从中国东北吉林省9个县（北纬40°52′至46°18′，东经121°38′至131°19′）采集了共计1235份猪血清样本，并通过间接血凝试验（IHA）检测弓形虫感染的血清阳性率。结果显示，弓形虫抗体阳性率为19.1%（95%置信区间[CI]，16.9%至21.3%），种公猪（28.6%，95%CI，20.0%至37.2%）和种母猪（32.0%，95%CI，25.2%至38.9%）的血清阳性率较高。在屠宰猪、育肥猪和仔猪之间未发现显著差异。这些结果表明，吉林省猪群中弓形虫感染普遍存在，且具有公共卫生意义。
