将患鸟毕吸虫病牛新鲜的粪便,分别盛于12个杯内。分为四组,每组三杯,其中一组各加一倍人尿,置于室温下(7—9℃),其余各组皆不加任何试验物,分别置于冰箱(-4～-6℃)、温箱(37℃)及室温下(7—9℃),观察虫卵死活,结果如下:1.病牛粪便不加任何试验物,置于室温下,虫卵可活至432小时;而置于温箱中经48小时虫卵全部死亡;同样置于冰箱内经24小时虫卵亦全部死亡。作者认为虫卵在吉林省的自然环境中不能过冬,因而春、夏季牛粪适当处理即成为防治措施的重要环节。2.牛粪与人尿各半混合,置于室温下经96小时虫卵全部死亡,此点与国内报告杀灭日本血吸虫卵的效果相符。
Bifidobacterium bird disease will be fresh feces, were Sheng Sheng 12 cups. Divided into four groups, each group of three cups, one of each group plus one times the urine, placed at room temperature (7-9 ℃), the remaining groups were without any test substance, were placed in the refrigerator (-4 ~ 6 ℃), incubator (37 ℃) and room temperature (7-9 ℃), observe the live and death of eggs, the results are as follows: 1.
