在血吸虫病防治、科研及教学工作中，为了了解自然草生地钉螺阳性或从大量钉螺中筛选出阳性钉螺供感染动物之用，常采用压碎钉螺镜检或小试管逸尾蚴等方法。前者工作量大且浪费阳性钉螺，后者需要大量小试管及纱盖，操作费时费力。多年来，我们使用废旧酶标板或细胞培养板筛选 In the prevention and treatment of schistosomiasis, scientific research and teaching work, in order to understand the natural habitat snails positive or from a large number of snails in the screening of positive snails for infected animals, crushing snails microscopy or small test tube often cercariae and other methods. The former is a heavy workload and a waste of positive snails, the latter requires a large number of small tubes and yarn cover, the operation time-consuming and laborious. For many years, we used discarded ELISA plates or cell culture plates for screening
