The prevalence, incidence and risk factors of infection by Echinococcus granulosus were studied in the domestic and street dogs of Kathmandu, Nepal. Using an ELISA coproantigen test as a screening method, the highest prevalence (5/88 = 5.7%) was seen in domestic dogs from an area of the city used for slaughtering livestock. A prevalence of 1.8% (3/171) was found in domestic dogs seen at eight veterinary clinics distributed around the city. Although none of the 73 street dogs sampled in the ELISA screening survey was positive, three of 20 street dogs killed with poison as part of the city's dog-control programme harboured from one to five adult worms. As none of 99 dogs treated with an anthelmintic was found re-infected 3 months later, it was impossible to calculate accurately the of infection over a 3-month period. Information about the feeding, sleeping and roaming practices of the dogs was also gathered using questionnaires and direct observations.
在尼泊尔加德满都的家养犬和流浪犬中，研究了细粒棘球绦虫感染的患病率、发病率及危险因素。采用酶联免疫吸附试验（ELISA）粪抗原检测作为筛查方法，在该市用于屠宰牲畜区域的家养犬中，患病率最高（5/88 = 5.7%）。在分布于全市的8家兽医诊所就诊的家养犬中，患病率为1.8%（3/171）。虽然ELISA筛查调查中采样的73只流浪犬均无阳性结果，但作为该市犬类控制计划一部分而被毒死的20只流浪犬中，有3只体内藏有1至5条成虫。由于99只接受驱虫治疗的犬在3个月后均未被再次感染，因此无法准确计算3个月期间的感染率。还通过问卷调查和直接观察收集了有关犬的饮食、睡眠和活动习性的信息。
