报道三平正肺吸虫生活史的虫卵发育过程,毛蚴的形态结构,第1中间宿主淡水螺的人工感染实验,以及三平正肺吸虫流行区淡水螺和第2中间宿主淡水蟹的剖检结果,证明放逸短沟蜷不是三平正肺吸虫的第1中间宿主.此外,发现平和华溪蟹和台湾南海溪蟹是其第2中间宿主.三平正肺吸虫(ParagonimuscenocopiosisChen)是陈心陶(1962)在广州郊区的锯齿华溪蟹(Sinopotamondenticulatus)的围心腔内发现其囊蚴(图9),经人工感染狗3个月后取得成虫而描述的.本虫囊蚴的排泄囊不越过腹吸盘(图5)和后尾蚴的火焰细胞数目72个为其显著特征.本种成虫的卵巢分支细而多(有2级和3级分支).左右睾丸呈星状,每睾有5～6个分叶,体棘簇生等为其主要鉴别特征.目前已知本虫在福建、江西、浙江等地各有报道(林宇光等1980、1983;林金祥等,1979;李友松等,1985).本虫的生活史尚未全面阐明.作者等于2001年对本虫开展生活史和其流行学的考察.
This paper reports the developmental process of Ophiogliomas, the morphological structure of miracidia, the artificial infection experiment of the first intermediate host freshwater snails, and the results of the necropsy of freshwater crabs and freshwater crabs from the endemic Pneumocystis tribe, It was proved that the drainage ditch was not the first intermediate host of P. sinensis.In addition, P. huaxiensis and S. nakai were found to be the second intermediate host of Paragonimus cenociopiosis Chen (1362) in Guangzhou The metacercariae were found in the pericardial cavity of Sinopotamondenticulatus in the suburb (Fig. 9) and were described by the adults infected with the dog 3 months after infection. The excretion of this metacercariae did not cross the abdominal sucker 5) and post-cercariae of the number of flame cells 72 as its distinctive features of the adult ovarian branch thin and more (with 2 and 3 branches) around the testis was star-like, each testis has 5 to 6 leaves , Body spine cluster as its main distinguishing features.It is known that this insect in Fujian, Jiangxi, Zhejiang and other places have been reported (Lin Yuguang et al 1980,1983; Lin Jinxiang et al 1979; Li You song et al 1985) The history has not been fully clarified. The author is equal to 2001 on this bug To carry out life history and its investigation of the epidemiology.
