【摘要】 目的　调查广西华支睾吸虫病的分布范围和流行特点。　方法　根据广西的不同地理位置及行政区划 ,随机选取调查点。用水洗沉淀法或醛醚集卵法粪检华支睾吸虫卵 ,并计算克粪便虫卵数 ;用玻片压碎法、压片法和人工消化法检查中间宿主淡水螺、鱼类的自然感染情况 ;用解剖动物找成虫或粪检查虫卵的方法了解保虫宿主感染情况。　结果　共调查 4 4个县 (市 ) 135个点 112 4 4 4人 ,人群平均感染率为 2 0 .15 % ,感染率随年龄增长而升高 ,男性高于女性 (P<0 .0 1)。第一中间宿主有赤豆螺、纹沼螺、长角函螺和硬豆螺 ;第二中间宿主有麦穗鱼、台细鳊等淡水鱼类 4科 32种。保虫宿主有猫、犬。人群感染方式以吃“鱼生”为主。　结论　广西华支睾吸虫病流行广泛 ,其中南部地区流行程度较重 ,呈“片状”分布 ;北部地区较轻 ,呈“点状”分布。更多还原

【Abstract】 Objective To investigate and determine the distribution and endemic characters of Clonorchiasis in Guangxi. Methods The investigated locations were selected according to geographical and administrative divisions of Guangxi; the eggs of Clonorchis sinensis in residents faces were examined and counted by formalin ether sedimentation or water washing precipitation methods; the natural infection of intermediate hosts including freshwater snails and fishes was examined by slide and artificial digestive methods; the infection of reservoir animals were detected by dissection or faces examination. Results 112 444 residents from 135 locations belonging to 44 counties and cities were examined, the average infection rate of C. sinensis is 20.15%; higher infection rate was seen in elderly and male residents ( P <0.01); the first intermediate hosts are Bithynia fuchsiana, Parafossarulus striatulus, Alocinma longicornis and Bithynia robusta ; freshwater fishes of 4 families including 32 species such as Pseudorasbora parva and Rasborinus formosae Ohima are the second intermediate hosts; cats and dogs are the reservoir animal; the disease is infected by eating raw or uncooked fishes. Conclusion C. sinensis was prevalent widely in Guangxi; the infection is higher in southern parts of Guangxi, with character of trip distribution, while the infection in northern part of Guangxi being patch distribution.更多还原
