目的了解湖南地区广州管圆线虫宿主及疫源地的分布。方法从野外、餐饮店、农贸市场等场所采集食用淡水螺、陆生螺、蛞蝓、虾、溪蟹、鱼和青蛙,用组织捣碎匀浆法及过筛沉淀法检查中间宿主、转续宿主体内的广州管圆线虫幼虫;解剖检查野鼠心肺广州管圆线虫成虫。结果7县(市、区)有5县(市、区)从野外捕获到福寿螺;3县从野外捕获中国圆田螺、中华圆田螺、方形环棱螺和蛞蝓,检查均未发现广州管圆线虫幼虫;7县(市、区)均未发现褐云玛瑙螺。6县(市)解剖褐家鼠、黄胸鼠、鼩鼱3种鼠,仅在1只褐家鼠的心脏和肺检获广州管圆线虫成虫8条。结论福寿螺在湖南南部地区分布广泛,首次证实湖南存在广州管圆线虫疫源地。
Objective To understand the distribution of the host and the foci of C. elegans in Hunan Province. Methods Edible freshwater snails, terrestrial snails, emus, shrimp, crab, fish and frogs were collected from wild places, restaurants and farmers’ markets. The intermediate hosts were examined by tissue homogenization and sieving. In vivo, C. elegans larvae were dissected; Results There were 5 counties (cities and districts) in 7 counties (cities and districts) captured wild snails from the wild in the 7 counties; 3 wild snails of Chinese snail, Chinese snail, Larvae; 7 counties (cities, districts) did not find brown cloud Agate spiral. 6 counties (cities) Anatomy of Rattus norvegicus, Rattus flavipectus, 鼩 鼱 3 kinds of mice, only 1 Rattus norvegicus in the heart and lung seized Aureobomycetemi adults 8.
