斯氏狸殖吸虫在犬体内多部位寄生与转换宿主的研究

Study on polyorganotropism and transfer host of pagumogonimus skrjabini in dog

目的:以斯氏狸殖吸虫囊蚴或童虫感染犬,定期解剖观察虫体。方法:经30、45、60、75、90和120d 分别解剖观察虫体在犬体内发育分布。结果:犬在感染囊蚴60d 后虫体可逐步发育成熟并产卵,豚鼠体内童虫经口感染犬,60d 时亦可在肺部查到虫囊和成虫。结论:斯氏狸殖吸虫在犬体多部位寄生且能发育成熟,童虫经感染犬宿主转换后,亦可进一步发育成熟。

Objeetive：To observe dogs infected with metalercariae and worms juveniles of pagumogonimus skrjabini. Methods：After that worms development, paraistic regions and morphological feature were observed at 30th,45 th, 60 th, 75 th, 90 thand 120 th day respectively. Results： 60 days after infection, worm-cysts wall, with matured or prematured worms and eggs. By means of host-transfer with worms juveniles,them migrated to the lung and matured. Conclusion： It is suggested that Pskrjabini could mature in dog and showed a phenomenon of polyorgamotropism.
