Higher infection rates were observed in gerbils and voles than in ICR mice after oral inoculation with eggs of a Japanese isolate of Taenia crassiceps. Asexual reproduction of T. crassiceps cysticerci was observed in all gerbils and voles infected i.p. with the cysticerci. However, ICR mice and Wistar rats were not suitable for the asexual proliferation of T. crassiceps. The hooks of cysticerci from mice were smaller than those from gerbils. In experimentally infected puppies, parasite development was noted as follows: strobilation and initial differentiation of the genital primordia on day 7 postinoculation (p.i.), appearance of the testes on day 9, observation of the ovaries on day 10, and development of the lateral branches of the uterus on day 15. The prepatent period was 27-31 days. After day 15 p.i., most of the worms were recovered from the middle third of the small intestine. The number of proglottids shed per day by each strobila was about 1. The number of eggs contained in a gravid segment was about 13,000.
用日本分离株肥胖带绦虫虫卵经口接种后，观察到沙鼠和田鼠的感染率高于ICR小鼠。腹腔接种肥胖带绦虫囊尾蚴后，在所有感染的沙鼠和田鼠中均观察到肥胖带绦虫囊尾蚴的无性繁殖。然而，ICR小鼠和Wistar大鼠不适合肥胖带绦虫的无性增殖。小鼠囊尾蚴的小钩比沙鼠的小钩小。在实验感染的幼犬中，观察到寄生虫发育情况如下：接种后第7天（p.i.）出现节片形成和生殖原基的初始分化，第9天出现睾丸，第10天观察到卵巢，第15天子宫侧支发育。潜伏期为27 - 31天。接种后第15天之后，大多数虫体从小肠中三分之一处回收。每个节片每天排出的孕节数量约为1个。一个孕节中含有的虫卵数量约为13000个。
