新疆温宿县家畜包虫病感染情况调查

Survey of Infections by Echinococcosis in the Livestock in Wensu

2011-2013年在新疆温宿县对家畜包虫病的流行现状进行调查。在定点屠宰场检查牛、羊包虫病感染情况;采集家/牧犬粪样在实验室用粪抗原夹心ELISA方法检测细粒棘球绦虫感染状况。表结表明2011-2013年家畜包虫病感染率分别为42.4%(336/793)、13.8%(30/217),11.5%(208/1817),平均感染率为20.3%(574/2827),三年家畜(牛、羊)的感染率感染率呈下降趋势,差异具有统计学意义(x2=332.338,P=0.000<0.01);2011-2013年犬细粒棘球绦虫阳性率分别为12%(30/250)、8.3%(20/240)和8.8%(21/240),平均感染率为9.7%(71/730),三年阳性率差异不具有统计学意义(x2=2.263,P>0.05)。三年调查结果表明家畜包虫病感染率呈下降趋势,但犬的细粒棘球绦虫感染率起伏较大。

Objective： The prevalence of Hydatid disease in the livestock of Wensu, Xinjiang was investigated from2011 to 2013. Method： The infection of Hydatid in cattle and sheep from slaughter houses was checked, and the infection of Echinococcus granulosus of home/herding fecal samples collected were detected by using the fecal Antigen sandwich ELISA method. Results： During 2011-2013, the infection rate of echinococcosis was 42.4% （336/793）, 13.8% （30/217）, 11.5% （208/1817）, respectively. This suggested an average infection rate of 20.3% （574/2827） and showed a statistically significant decrease in the infection rate （x^2=332.338, P= 0.000〈0.01）. Meanwhile, the infection rate of echinococcus granulosus in dogs was 12% （30/250）, 8.3% （20/ 240） and 8.8% （21/240）. The average infection rate was 9.7% （71/730） which was not statistically significant （x^2=2.263, P〉0.05）. Conclusion： These results illustrated that there was a decline in Hydatid infection in livestock; while there was an increase in the infection rate of Echinococcus granulosus infection in dogs.
