摘要:

目的: 探讨卫氏并殖吸虫和斯氏狸殖吸虫在禽、蛙体内的分布与发育, 以及童虫对终宿主的侵袭力。方法: 从江西、广东两省并殖吸虫流行区采集溪蟹, 分离囊蚴。以每只动物30-200 个囊蚴分别感染雏鸡、雏鸭、鹌鹑、鹦鹉和蛙, 定期剖检。将禽、蛙体内所获童虫经口感染犬或猫, 60 d 后剖检, 观察虫体发育情况。结果: 两种并殖吸虫均可在鸡、鸭、鹌鹑和鹦鹉体内存活,虫体分布于体腔、肝脏、肺和肌肉。所有虫体为小型滞育童虫。斯氏狸殖吸虫对蛙的感染率为1.7%- 40.0% , 未查见卫氏并殖吸虫感染蛙。童虫经宿主转换后, 在犬、猫胸腔或肺虫囊内检获虫体,除部分为成熟前期虫体外, 多数为含卵成虫。结论: 在流行区, 禽和蛙在人体并殖吸虫病传播中的作用, 应予重视。

Abstract:

AIM: To explore the distribution and development of Paragonimus westermani and Pagumogonimus skrjabini in fowls and frogs in addition to the invasiveness of the juveniles recovered from the above animals to cats or dogs. METHODS: Chickens, ducks, quails and parrots were infected orally each with 30 - 200 metacercariae of Paragonimus westermani and Pagumogonimus skrjabini, respectively. Dogs or cats were infected with juveniles obtained from the above animals. RESULTS: Juveniles were obtained from body cavities, livers, lungs and muscles of fowls and frogs 60 days after infection. Most of the juveniles were detected from the muscles but their development retarded. In 60 frogs infected with metacercariae of Paragonimus westermani, no worm was found. Infection rate of frogs infected with Pagumogonimus skrjabini was1.7% - 40.0%. After host transfer, juveniles developed well and matured in the thoracic cavities or lung worm cysts of dogs or cats, but some prematured worms were also detected. CONCLUSION: Attention should be given to the role of fowls or frogs in the transmission of human paragonimiasis in endemic area.
