湖北肋壳钉螺与云南大理光壳钉螺的外形有显著差异,交互感染实验结果也有差异。郭源华等(1963)认为它们分别属于不同的组。刘月英等(1974)将它们列为“湖北钉螺”与“光钉螺”两个独立的种,1979年又改为“钉螺指名亚种”与“钉螺滇川亚种”。本文用从它们逸出的尾蚴对实验感染小鼠的致病力及虫体在鼠体内发育的情况。进行了比较研究。 There were significant differences in the appearance of snails in Hubei rib shell snail and Yunnan Dali shell, and the results of reciprocal infection were also different. Guo Yuanhua (1963) that they belong to different groups. Liu Yueying et al. (1974) listed them as two independent species, “Snail Snail” and “Snail Snail”. In 1979, they were renamed as “Snail Snail” and “Snail Snake.” In this paper, the cercariae escaped from them were used to test the virulence of mice infected with cercariae and the development of parasites in mice. Conducted a comparative study.
