作者在不同时间以四环素水喂饲长爪沙鼠观察其对彭亨丝虫发育的影响,以评价其预防效果。 第一次实验以1.4％(W/V)四环素水于沙鼠感染前30d至感染后30d连续用药。从埃及伊蚊收集彭亨丝虫第三期幼虫(L_3)100条皮下感染沙鼠,感染后60d计数成虫。第二 At different times the authors fed tetracycline water Mongolian gerbils to observe its impact on the development of Paeni filariasis to evaluate its preventive effect. In the first experiment, tetracycline water at 1.4% (w / v) was administered continuously from 30 days prior to gerbil infection to 30 days after infection.
