摘要: 2008年4~11月在河南省漯河市开展曼氏裂头蚴病流行病学调查。现场采集并检测中间宿主感染情况,包括显微镜检查剑水蚤体内曼氏迭宫绦虫原尾蚴,解剖镜下观察青蛙和蝌蚪皮下、肌肉组织和内脏感染裂头蚴的状况。水洗沉淀法收集终宿主家猫和犬粪便,镜检计数虫卵。收集蝌蚪体内的裂头蚴灌胃感染家猫,观察其排卵情况。结果显示,剑水蚤、蛙类和蝌蚪的感染率分别为3.5%(3/85)、35.9%(120/334)和16.8%(75/446)。调查家猫3只、犬31只,分别有1只和6只(19.4%)感染曼氏迭宫绦虫。感染家猫裂头蚴后12 d粪检,曼氏迭宫绦虫卵阳性,25 d自小肠取出17条曼氏迭宫绦虫成虫。表明河南省漯河市为曼氏裂头蚴病疫源地,终宿主和中间宿主感染率均较高。当地居民有生食蝌蚪的不良习俗是感染曼氏裂头蚴的主要原因。

Abstract: The investigation was made in Luohe City of Henan Province from April to November, 2008. Cyclops were collected and plerocercoids of Spirometra mansoni were examined by microscope. Skin, muscle and internal organs of frogs and tadpoles were checked to detect spargana by naked eye and/or anatomical microscope. Feces of cats and dogs were collected to examine eggs after washing and precipitation. Spargana from tadpoles were collected to infect cats by oral inoculation. Results showed that the infection rate of plerocercoids in cyclops was 3.5%(3/85) and that of spagarna in tadpoles and frogs was 35.9% (120/334) and 16.8%(75/446), respectively. Among 3 cats and 31 dogs investigated, 1 and 6 (19.4%) were found infected respectively. Eggs of Spirometra mansoni were found in feces of cats 12 days after infection. 17 adult worms were found in the intestine of the cat on the 25th day. The habit of eating live tadpoles was found in local residents. The investigation reveals a high prevalence of Spirometra mansoni in the intermediate and final hosts. Eating live tadpoles seems a main reason of getting sparganosis mansoni.
