用蚴龄5.5～22天的钩蚴感染半年以上的仓鼠,共感染30只,雌18只,雄12只,每鼠经右侧腹股沟皮下接种幼虫400条。感染后自24小时至134天之内杀死仓鼠,观察结果: 1、在感染后24小时幼虫即移行至肺脏,自1～9天肺脏幼虫较多,以后渐少,但在60天后肺脏仍有幼虫,自感染后7天幼虫开始移行至小肠。自1～134天在接种侧均可检出幼虫,尤以接种的局部较多。2、共接种30只仓鼠,幼虫移向未接种侧的14只,占47%。在14只中共检出幼虫252条,其中接种侧229条,占90.9%,对侧23条,占9.1%,另16只在接种侧检出175条,对侧未检出。
Hamsters infected more than half a year with metacercariae larvae aged 5.5 to 22 days larvae were infected with 30, 18 females and 12 male rats. 400 larvae were subcutaneously inoculated into the right groin in each rat. After infection, the hamsters were killed within 24 hours to 134 days. The results were as follows: 1. The larvae migrated to the lungs 24 hours after the infection. Since 1 to 9 days, Larva, larvae migrate to the small intestine 7 days after infection. From 1 to 134 days in the inoculation can be detected larvae, especially inoculation of the local more. 2, a total of 30 hamster inoculation, the larvae moved to the uninoculated side of 14, accounting for 47%. Of the 14 CCPs, 252 larvae were detected, of which 229 were inoculated, accounting for 90.9%, contralateral 23, accounting for 9.1%, and the other 16 were 175 on the inoculation side but not on the contralateral side.
