目的 查清广西主要林区并殖吸虫病自然疫源地分布及虫种。方法 解剖蟹类分离囊蚴并感染动物获取成虫鉴定虫种、玻片压碎法镜检螺类自然感染尾蚴、粪检或解剖动物查找虫卵和成虫了解动物宿主感染、以成虫抗原作ＩＤ及ＥＬＩＳＡ，结合痰液和粪便检查确定人体感染。结果 在３７ 县（市）检查蟹类４ 科８ 属２０ 余种共２０２０８４ 只，有１５县（市）从圆顶华溪蟹等８ 种共１２７５ 只蟹中查获并殖吸虫囊蚴，自然感染率在０．１～２２．２％ 之间；检查淡水螺类４４８４７ 只，携带并殖吸虫尾蚴１５７ 只，自然感染率在０．３％ ～０．４％ 之间；检查６ 种动物粪便、内脏４０８份和１６ 份，发现果子狸等３ 种动物的１７ 份粪便中有并殖吸虫卵。那坡、资源、兴安和融水４县有人体感染病例２５ 人。根据囊蚴及成虫的形态特征初步鉴定有斯氏、异盘、巨睾和白水河（或歧囊）４ 种并殖吸虫。结论 桂西、北山区广泛存在并殖吸虫病自然疫源地，斯氏并殖吸虫是当地的优势虫种，分布于融水、龙胜等１３ 个县
Objective To investigate the distribution and insect species of natural foci of paragonimiasis in major forest areas in Guangxi. Methods Anatomy of crabs from metacercariae and infection of animals Obtained adult worms Identification of worm species, glass slide crush Microscopy Natural infection of cercariae, fecal examination or dissection of animals to find eggs and adults Understanding of animal host infections, adult worms as ID and ELISA, combined with sputum and fecal examination to determine human infection. Results In 37 counties (cities), there were 20,204 species of 8 genera and 4 genera in 4 families and 15 families (cities) were found from 1275 crabs, including 12 domestication crabs. The rate was between 0.1% and 22.2%; 44847 freshwater snails were examined, 157 cercariae were harvested and the natural infection rate was between 0.3% and 0.4%; 6 kinds of animal excrements, 408 copies and 16 viscera, and found that there were Paragonimus eggs in 17 of the three kinds of animals including civets. That slope, resources, peace and melt water 4 counties have human infection cases 25 people. According to the morphological characteristics of metacercariae and adults, four species of Paragonimus spp. Conclusions The natural foci of paragonimiasis exist widely in Guangxi and Beishan areas. Paragonimus spp. Is the predominant species of insects, distributed in 13 counties such as Rongshui and Longsheng
