三平正并殖吸虫(Euparagonimus cenocopiosus)自陈心陶等(1965)报告后,近年来陆续在福建、浙江等地发现其囊蚴(李友松等,1980;孟文贤等,1980);并对其形态、染色体核型等展开了研究(何毅勋等,1982;彭德华,1984;雷昌球等,1983),然而对其中间宿主的感染情况,及其在流行区的感染强度等,迄今所知甚少。为此,我们于1984年1—6月,前后5次深入流行区,开展调查研究,现将结果报告如下。材料和方法所用溪蟹标本,均采自松阳县安民乡大潘坑村一条窄溪,此地系瓯江上游一侧流的源头。
Euparagonimus cenocopiosus, after its report by Chen Xintao et al. (1965), discovered the metacercariae successively in Fujian and Zhejiang provinces in recent years (Li Yousong et al., 1980; Meng Wenxian et al., 1980); and studied its morphology, (He et al., 1982; Peng et al., 1984; Lei Changqiu et al., 1983). However, little is known about the infection status of their intermediate hosts and the intensity of their infection in endemic areas. For this reason, we carried out investigation and study on the five-point epidemic area from January to June 1984, and the results are reported as follows. Materials and methods used crab specimens, are collected from An Min Township, Songyang County, a small stream Pan Hang Village, here on the upstream side of the Oujiang stream source.
