The percentage infection rate, worm burden and worm recovery rate in mice increased with an increase in the duration of exposure to cercariae. However, mice exposed to cercariae for 4 min had the same worm burden and worm recovery rates as those exposed for 16 min. Mice exposed to 80 and 160 cercariae each exhibited the highest percentage infection rates. The worm burden was highest in mice exposed to 160 cercariae each, while the worm recovery rate was highest in those exposed to 80 cercariae per mouse.
小鼠的感染率、虫负荷和虫回收率随尾蚴暴露时间的增加而升高。然而，暴露于尾蚴4分钟的小鼠与暴露16分钟的小鼠具有相同的虫负荷和虫回收率。暴露于80只和160只尾蚴的小鼠均表现出最高的感染率。每只暴露于160只尾蚴的小鼠虫负荷最高，而每只暴露于80只尾蚴的小鼠虫回收率最高。
