摘　　要：以不同数量的斯氏狸殖吸虫(Pagumogonimus skrjabini)囊蚴,经口感染豚鼠、家兔、黑斑蛙、虎纹蛙、雏鸡,不同时期分批解剖。在动物的体腔、肺、肝、肌肉等部位,均检获虫体。豚鼠、家兔体内虫体的发育,出现分化。有发育缓慢、排泄囊内充满黑色颗粒的小型童虫,也有部分发育迅速、已具生殖器官雏形的大型童虫。蛙和鸡感染后,虫体多分布于肌肉和肝脏。将上述动物体内不同时期所获得的小型童虫,分别经口感染家犬,70d后均从犬肺部检获成虫。结果表明,转续传播或宿主转换是斯氏狸殖吸虫另一传播方式。Guinea pig, rabbit, frog and chicken infected orally with metacercariae of Pagumogonimus skrjabini were carried out in our laboratory. Worms were detected in body cavi- ties, livers, lungs and museles of guinea pigs and rabbit,some worms developed quickly and early reproductive organs can be clearly observed, while others recovered from muscles were similar to excysted metacercariae. In frogs and chickens juveniles were detected in body cavity, liver and muscles. All worms were small type juveniles. Small type juveniles obtained from guinea pigs, frogs and chickens were transferred orally to suitable host dogs,they matured in lungs. The re- sults showed that different animals infected with P. skrjabini can induce transmission of Pagu- mogonimiasis skrjabini.
