中文摘要:
      为了解湖南省羊弓形虫病流行情况,2017年采用间接血凝试验(IHA),对邵阳、常德、湘潭、岳阳、株洲、郴州、张家界、娄底等8个地区进行山羊弓形虫血清学调查。结果显示:共采集的5 600份羊血清中,检出弓形虫血清抗体阳性468份,样品阳性率为8.36%,其中2017年上半年阳性率为8.75%,下半年为7.96%,无明显季节性差异(P>0.05);在抽检的216个场户中,检出阳性场户102个,场群阳性率为47.22%,其中散养户的场阳性率与样品阳性率(分别为64.61%、12.04%)高于规模场(分别为39.73%、7.14%),差异显著(P<0.05);1岁以上成年羊(10.77%)和1~6月龄(9.28%)幼年羊的样品阳性率明显高于7~12月龄的青年羊(5.93%),差异极显著(P<0.01);8个地区的样品阳性率有差异,其中邵阳市最高(10.00%),常德市最低(6.42%)。调查结果表明,弓形虫感染在湖南省羊群中较为普遍,各地区羊群中均存在不同程度的感染,因此湖南省应注意加强弓形虫监测与防控,尤其是散养和1岁以上成年羊群,以确保公共卫生安全。
英文摘要:
      In order to investigate the prevalence status of Toxoplasma gondii infection in goatssheep,in 2007,by indirect hemagglutination assay,a serological survey was carried out in 8 districts of Hunan Province,including Shaoyang,Changde,Xiangtan,Yueyang,Zhuzhou,Chenzhou,Zhangjiajie and Loudi. According to the results,a total of 5 600 sheep blood samples were collected,468 of them were detected positive antibodies against Toxoplasma gondii,with the positive rate of 8.36%. Furthermore,the antibody positive rate in the first half year of 2017 was 8.75%,and the rate in the second half year was 7.96%,no obvious difference was found among different seasons. In terms of the 216 tested farms and households,positive serum samples were found in 102 of them,the positive rate at the farm level was 47.22%. The positive rates of households at the farm and individual level(64.61%,12.04%)were all higher than those of large-scale farms(39.73%,7.14%),the difference was significant(P<0.05). In addition,the positive rates of samples from goats over 1 years old(10.77%)and at the age of 1 to 6 months(9.28%)were obviously higher than that of samples from goats at the age of 7 to 12 months(5.93%),the difference was extremely significant. Positive rates of samples in the 8 districts were also different,it was highest(10.00%)in Shaoyang City and lowest(6.42%)in Changde City. In conclusion,infection of Toxoplasma gondii was relatively common in goats in Hunan Province,different degree of infection existed in various districts. Therefore,Toxoplasma gondii surveillance and control towards goats in Hunan Province should be strengthened,especially the back-yard goats and adult goats over 1 year old,so as to ensure the public health security.
