Abstract
A female prairie rattlesnake (Crotalus viridis viridis) was gastric intubated with 250 tetrathyridia of Mesocestoides sp. The snake was killed 12 wk postinfection; a portion of the liver was examined histologically for evidence of tetrathyridia. Five tetrathyridia were seen in two hepatic portal triad vessels. We propose that a blood-borne metastasis of tetrathyridia in reptiles and rodents may occur.
摘要
一条雌性草原响尾蛇（绿响尾蛇指名亚种）经胃插管接种了250个中殖孔绦虫四膜虫型幼虫。在感染后12周处死该蛇；取部分肝脏进行组织学检查以寻找四膜虫型幼虫的证据。在两个肝门三联管血管中发现了五个四膜虫型幼虫。我们认为，四膜虫型幼虫在爬行动物和啮齿动物中可能会发生血行转移。
