斯氏狸殖吸虫囊蚴经口感染家兔、小鼠、豚鼠和大鼠,25～120d分期解剖。重点观察肺部虫囊有无成虫及虫卵,以寻求适宜的宿主作为斯氏狸殖吸虫的实验动物。检查结果家兔、小鼠和豚鼠在接种后死亡甚多。均未查到成虫,仅见童虫。接种38只大鼠,感染60d即在肺部出现虫囊;感染90d及110d的肺部虫囊检出童虫及少部分成虫;感染120d时,87.5％虫体成熟,且成虫及卵的形态与感染犬体的斯氏狸殖吸虫的形态相似。提示大鼠是建立斯氏狸殖吸虫动物模型的理想动物。 Sturgeon genitalium metacercariae infected rabbits, mice, guinea pigs and rats, 25 ~ 120d stage dissection. Focus on the observation of lung worms with or without adult worms and eggs in order to seek suitable host as a laboratory animals of the genus Trichogramma. Test results Rabbits, mice and guinea pigs died after vaccination. Did not find adults, only see the pest. Inoculation of 38 rats, 60 days after infection in the lungs that the worm capsule; 90d and 110d infection of the lung worm capsule and a small number of adult worms detected; infected 120d, 87.5% of the parasites mature, and adult and egg morphology Similar to the morphology of the infected genus Trichogramma. It is suggested that the rat is an ideal animal to establish the animal model of.
