摘要Abstract
Normal and immunosuppressed mice were infected with oncospheres of Taenia saginata asiatica and T. solium. Although normal ICR mice were not susceptible to these 2 parasites, cysticerci were recovered from the immunosuppressed ones following venousinjection. For T. saginata asiatica, immunosuppressed ICR mice had an infection rate of 12.5% and 6 cysticerci of this parasite were recovered from 3 males. After injection of T. solium oncospheres, a high infection rate of 57% was obtained and 23 cysticerci were collected from 13 male immunosuppressed ICR mice. The immunosuppressed C57 mice had the highest infection rate (100%) and cysticercus recovery rate (2.4%) for T. solium. The infection rate and cysticercus recovery rate in 6 normal C57 mice were40 and 3%
respectively. The immunosuppressed ICR, BALB/c and C3H mice were also susceptible to T. saginata asiatica.
