摘　　要：目的了解河南省部分地区蛙类曼氏裂头蚴感染情况。方法 2008～2011年在河南省不同地区的农村池塘及农贸市场采集蛙类,剖检曼氏裂头蚴,记录其寄生部位和感染数量,并进行统计学分析。结果共采集并检查黑斑蛙、泽蛙、林蛙、蟾蜍及蝌蚪等4 848只,其中感染曼氏裂头蚴者728只,总感染率15.02%,发现曼氏裂头蚴4 034条,平均感染强度为5.54条/只。不同种类的蛙中以泽蛙的感染率最高(20.82%);多数虫体(76.37%)的寄生部位为后腿肌肉;有病例地区的蛙类感染率(18.36%)高于无病例地区(12.38%)(P<0.05);市售蛙类的感染率为11.71%(295/2520)。结论河南省蛙类感染曼氏裂头蚴的情况较为普遍,进食不熟的蛙肉或吞服活蝌蚪具有感染裂头蚴的高度危险性。Objective To survey the Sparganum mansoni infection in frogs from different areas of Henan Province.Methods From 2008-2011,wild frogs and frog tadpoles were collected from rural ponds and markets in different areas of Henan Province and dissected.The spargana were examined and isolated,and the site of the parasite and number of spargana collected were recorded and analyzed with a statistical software package.Results A total of 4 848 of wild frogs（Rana nigromaculata,R.limnocharis,R.temporaria,and toads） and frog tadpoles were examined by necropsy;728（15.02%） frogs and tadpoles were infected with sparganum,4,034 spargana were collected,and the mean density of infection was 5.54 worms per frog（or tadpole）.Of these frogs,20.82% were R.limnocharis,which had the highest infection rate.Most（76.37%） plerocercoids were located in the muscles of the hind legs.The infection rate（18.36%） of frogs from areas with sparganosis was higher than that（12.38%） of frogs from areas with no sparganosis（P0.05）.In addition,wild frogs sold at market had a sparganum infection rate of 11.71%（295/2520）.Conclusion S.mansoni infection in frogs is common in Henan Province.The consumption of the insufficiently cooked meat of frogs or live tadpoles poses a high risk of sparganum infection.
