摘要: 本文应用卡松尼皮内试验(ID)、间接红细胞凝集试验(IHA)和B超3种检测技术方法,对青海省玉树藏族自治州称多地区藏族820人作了血清学调查。结果ID和人IHA的阳性率分别为21.0%和11.7%;B超检查813例,确诊现症患者41例,均为囊性包虫病。结果表明,人群棘球蚴感染率和患病率均以女性牧民为最,这可能与牧业区藏族妇女担负繁重的生产和家务劳动,频繁接触家犬及其污染物有关。在年龄分布上,有随年龄增加而感染与患病水平逐升之趋势。该地区无主犬细粒棘球绦虫的带虫率高达36.1%(30/83)。牛和羊细粒棘球绦虫平均感染率分别为52.7%(544/1033)和35.0%(418/1193)。结果证

Abstract: This paper presents high prevalence of hydatid disease in humans and animals in Chenduo, Qinghai. By using Casoni's intradermal test (ID), indirect hemagglutination assay (IHA), and B mode ultrasonography, 820 Zans living in Chenduo were examined for hydatid disease. The positive rates assayed by the three methods were 21.0%, 11.7% and 5.0%, respectively. Forty one cases were found to harbor cystic hydatid. The infection rate was higher in females than in males, because Zang women had more chance to contact with dog and its excreta; besides, the infection rate was increasing with age. Concurrent survey of animals showed Echinococcus granulosus infection rate of 36.1% in dog, and hydatid infection rates of 52.7% and 35.0% in yak and sheep, respectively. The establishment of this parasite in dog sheep and dog yak cycles was revealed. Wild rodent Ochotona curzoniae with infection rate of 3.5% was found to be one of the intermediate hosts of E. multilocularis. Further study on E. multilocularis in domestic and/or wild animals is required.
