本文用卫氏并殖吸虫(P.W.)囊蚴经口感染恒河猴、家猪、山羊、家兔、豚鼠、小白鼠、青蛙等七种动物,观察其病理变化及虫体的发育情况。除青蛙外,其他六种动物均被感染。基本病变为幼虫移行处引起的点状出血、纤维素性炎、窦道及死虫结节。虫体发育远较犬、猫等适应宿主为差,且大部分位于腹、背部肌肉中。根据前人及本实验结果提示所有哺乳动物均可感染,食肉兽均可能为P.W.的终宿主,食草兽均可能为P.W.的转续宿主。人类P.W.不适合寄生型在人体内的适应程度介于食肉兽及食草兽之间。本文讨论了动物界P.W.幼虫移行症与本病的流行关系。
In this paper, Paw Paragonimus (P.W.) metacercariae were infected with rhesus monkeys, domestic pigs, goats, rabbits, guinea pigs, mice, frogs and other seven animals, to observe the pathological changes and the development of parasites. Apart from the frog, all six other animals were infected. The basic lesions caused by migratory larval punctate bleeding, fibrinitis, sinus and dead nodules. Insect development far more than dogs, cats adapt to the host is poor, and most are located in the abdomen, back muscles. According to the predecessors and the experimental results suggest that all mammals can be infected, the carnivore may P.W. of the final host, herbivore may P.W. Human P.W. Not suitable for parasitic in the human body to adapt to the level between the carnivore and herbivore. This article discusses the prevalence of P.W. larvae in the animal kingdom and its prevalence.
