【摘要】 <正>叶形棘隙吸虫(Echinochasmus perfoliatus Ratz, 1908)主要寄生于犬、猫等动物,在日本(Hiraswa, 1928)与我国(武汉医学院寄生虫学教研室,1979;徐秦锟、李道宁,1979;林金祥、程由注,1980)曾报道人体感染。其第一中间宿主是纹沼螺(Parafossorulus striatulus)(Ciurea(1920)、Tang(1936)、Komiya(1951))。1985年11～12月作者在福建龙海县步文乡居民附近池塘内采集的铜诱环棱螺(Bellamya aeruginosa)体内,发现一种具棘口科吸虫特征的尾蚴,并作了动物感染实验观察,证明其为叶形棘隙吸更多还原

【Abstract】 This paper reports the discovery of the cercaria which is similar to that of Echinostomatidae in the Bellamya aeruginosa in Longhai County of Fujian.Cysts formed in fresh-water fish gills after experimentaly infected with cercariae for 3 to 4 hours. Adult worms were obtained from Mesocricetus aurafus after infection with cysts, which were identified as Echinochasmus perfoliatus. Bellamya aeruginosa in a new first intermediate host of Echinocgasmus perfoliatus. The number of snails examined wes 452, with average nature positive infection rate of 22.6%.更多还原
