陕西省姜片吸虫病疫源地的病原研究

1.本文结合陕西省姜片吸虫病疫源地的研究,进行了病原-布氏姜片吸虫〔FaseioIops is bus ki(Lankester,1557)odhner,1902〕的形态和生物学方面的一些工作.2.通过虫体整体标本的观察,较详细地研究了姜片吸虫成虫形态。 3.本文详细观察和描述了姜片吸虫各期幼虫的形态和发育并与广东的相同资料作了比较讨论,关于成虫的发育观察详另一报告。 4.实验证明:陕西省友中地区在七、八月份室温平均26.32-26.49Oc时,布氏姜片吸虫卵的发育良好,需23天内毛坳成熟,而在室温平均13,21。C时(十一月份),则虫卵停止发育。

STUDIES ON THE PATHOGENS OF THE SHANSI FASCIOLOPSASIS NIDUS

1. The present paper records some works on the morphology and biology of one of the elements of a Fasciolopsiasis nidus located at the Shansi province, i.e.the causative agent, Fasciolopsis buski (Lankester, 1857) Odhner, 1902. 2. The morphological features of the adult worms were studied in detail. 3. The morphological features and the development of various stages of the trematode were observed and described in detail. To compare those observed with Kwangtung specimens, a discussion was finaily presented. As to the development of the adult flukes in vivo, see another report of the series. 4. Experimental observations revealed that at Hangchung district, Shansi province, where the nidus was found, the eggs of the said intestinal flukes developed very well in July and August when the average room temperature were 26.32-26.49℃. In this case, 23 days were needed for the full growth of the miracidia, while in November when the average room temperature was only 13.21℃., the fluke eggs' ceased to develop.
