【摘要】：为掌握北京市郊区猪弓形虫的感染情况及流行趋势,于2014年1—12月份共分4次采集北京市郊区不同养殖环境养殖场、不同生产阶段和不同季节的猪的血清样本655份,采用间接血凝试验(IHA)检测了血清中的弓形虫抗体。结果表明:在受检的655份猪血清样本中,阳性样本191份,弓形虫感染阳性率为29.16%;按不同养殖环境统计,规模猪场的阳性率为22.26%,养殖合作社的阳性率为32.50%,散养户的阳性率为37.27%;按不同生产阶段统计,保育猪为16.80%,育成猪为22.96%,育肥猪为26.67%,后备母猪为37.60%,经产母猪为41.38%,种公猪为20.00%;按采样季节统计,猪弓形虫抗体阳性率春季为24.52%,夏季为36.21%,秋季为35.63%,冬季为18.71%。根据调查结果判断,各种来源的猪均有不同程度的弓形虫感染,散养户比规模猪场感染率高,夏季和秋季的感染率明显高于冬季和春季。血清学调查结果与国内部分省(市)报道相符。
[Abstract]:In order to know the infection situation and epidemic trend of Toxoplasma gondii in Beijing suburb, 655 serum samples of pigs in different breeding environment, different production stages and different seasons were collected in January and December 2014. Toxoplasma gondii antibody in serum was detected by indirect hemagglutination test (IHA). The results showed that the positive rate of Toxoplasma gondii infection was 29.166.The positive rate of Toxoplasma gondii infection was 29.160.The positive rate of Toxoplasma gondii infection was 29.160.The positive rate of Toxoplasma gondii infection was 29.@@ The positive rate of large-scale pig farm was 22.26. The positive rate of farming cooperative was 32.50. The positive rate of scattered farmers was 37.27. According to the statistics of different production stages, The positive rate of Toxoplasma gondii antibody was 24.52 in spring, 36.21 in summer, 35.63 in autumn, 18.71 in winter. According to the results of the investigation, the infection rate of Toxoplasma gondii in pigs from various sources was higher than that in large pig farms, and the infection rate in summer and autumn was significantly higher than that in winter and spring. The results of serological investigation were consistent with the reports of some provinces (cities) in China.
