作者对血吸虫在宿主体内发育过程中移行经过肺部毛细血管时是否可以引起肺炎症进行了动物实验。田鼠初次感染小量曼氏血吸虫尾蚴(50条),经过不同间歇时间后再给250条尾蚴作攻击感染,在第5天从肺部收集到的童虫数量远低于正常田鼠(未经免疫感染)在接受攻 The authors performed animal experiments on whether schistosoma could cause lung inflammation when migrating through the pulmonary capillaries during development in the host. Microtus mansoni (50) were infected for the first time by a vole, and 250 cercariae were challenged after different intervals. The number of squirrels collected from the lungs on day 5 was much lower than that of the normal vole (unimmunized Infected) in the attack
