谷重和等首先在日本秋田县发现圆圃棘口吸虫(Echinostoma hortense Asada,1926)疑似病例,有薗直树等在日本报告4例,并从泥鳅(Misgurnusanguillicudatus)中取得囊蚴实验感染犬和人成功,从而证实日本产泥鳅为该虫第二中间宿主。同年,谷重和在秋田县发现14例吃生泥鳅的感染病例。 作者等(1989)首次报告我国因吞活泥鳅感染该虫的病例,并对驱出虫体作了形态观察。我国福建已报告该虫第二中间宿主为沼蛙(Rana guenthe-ri)。为证实我国产泥鳅是否也是第二中间宿主,1989年8—11月,对哈尔滨市等3地泥鳅进行了该
Tachikatsu et al. First found suspected cases of Echinostoma hortense Asada (1926) in Akita prefecture, Japan. Four cases were reported in Japan, such as Namphaea japonica, and the infection of dogs and humans with metacercariae from Misgurnus anguillicudatus Success, which confirmed that the Japanese loach for the second intermediate host. In the same year, Taniguchi and found 14 cases of raw loach infection in Akita Prefecture. The author (1989) for the first time reported in our country due to loach inactivation of the worm infection cases, and the morphology of the worm was observed. Our country, Fujian, has reported that the second intermediate host to this pest is Rana guenthe-ri. To confirm whether the loach produced in our country is also the second intermediate host, from August to November 1989, three loaches in Harbin City were carried out
