斯氏狸殖吸虫感染多种动物及体内发育的研究

目的 :以不同数量斯氏狸殖吸虫囊蚴 ,分别感染大白鼠 ,小白鼠和豚鼠 ,定期解剖观察虫体。方法 :经1 5、30、45、60、75、90、1 1 0和 1 2 5d分别解剖观察虫体在实验动物体内发育 ,分布及虫体检出率。结果 :大鼠在感染 90d后虫体可以逐步发育成熟并产卵 ,而小白鼠和豚鼠体内只能查到童虫阶段。结论 :初步证实大白鼠是斯氏狸殖吸虫的适宜宿主 ,小白鼠和豚鼠体内的虫体全部处于滞育阶段 ,不能发育为成虫

Studies on Experimental Infection to Different Animals and Development of Pagumogonimus Skrjabini

Objective To observe rats, guinea and mices infected with metalercariae of pagumogonimus skrjabini. Methods After that worms development, paraistic regions, morphological feature and detectable rate were observed at 15th, 30th, 45th, 60th, 75th, 90th, 110th and 125th day respectively.Results Mices and guinea pigs inoculated orally with metalercaria of pagumogonimus skrjabini and stunted juveniles were obtained from body, the morphology and structure of the stunted juveniles are similar to those of excysted metalercariae even 110 days after infection. Conclusion This indicated that rats are suitable host of pagumogonimus skrjobini, while mice and guinea pigs arel not.
