目的掌握甘南藏族自治州中间宿主棘球蚴感染状况,为本地区包虫病的传播动力学研究及开展大规模包虫病防治做好前期工作。方法对碌曲县和玛曲县当地牦牛、绵羊作包虫病病原学检查,记录囊肿大小、数量、寄生部位及性质等,并用10%甲醛溶液固定,做病理切片检查。结果剖检绵羊4309头,细粒棘球蚴感染率为10.61%(457/4309),多房棘球蚴感染率为0.14%(6/4309);剖检牦牛3645头,细粒棘球蚴感染率为9.16%(334/3645),多房棘球蚴感染率为0.14%(5/3645)。结论该地区牦牛及绵羊细粒棘球蚴感染率较高,并有多房棘球蚴感染。
Objective To understand the status of hydatid cysts in the intermediate host of Gannan Tibetan Autonomous Prefecture and to make preliminary studies on the transmission dynamics of hydatid disease in the region and prevention and control of large-scale hydatid disease. Methods The local yaks and sheep in Luqu County and Maqu County were examined for echinococcosis by echinococcosis. The size, number, parasitic sites and nature of cysts were recorded and fixed with 10% formaldehyde solution for pathological examination. Results 4309 sheep were dissected, the infection rate of Echinococcus granulosus was 10.61% (457/4309), the infection rate of Echinococcus multilocularis was 0.14% (6/4309) The infection rate was 9.16% (334/3645), and the echinococcosis infection rate was 0.14% (5/3645). Conclusions The infection rate of Echinococcus granulosus in yak and sheep in this area is high, and there are many cases of echinococcosis infection.
