在血吸虫病流行区检查自然水体(江、湖、河、塘)中的血吸虫尾蚴以了解疫水的感染程度,正如像检验自然水体中的细菌指数以了解水体污染程度一样,本应是卫生防疫检验的一项基本方法。但因过去调查自然水体的血吸虫尾蚴常用小白鼠感染法,既化费人力物力较大,又需20多天后才得调查结果,不能立即了解疫水的感染程度,不能推广于一般单位应用。我们近年来试用粘触沉淀法(简称粘取法)检查自然水体中的血吸虫
Schistosoma japonicum cercariae in natural waters (rivers, lakes, rivers, and ponds) are examined in areas endemic for schistosomiasis to understand the extent of infection with water, just as it is to examine bacterial indices in natural waters to understand the extent of water pollution, which should be hygienic and epidemic prevention A basic method of testing. However, due to the past investigation of natural water Schistosoma japonicum cercariae commonly used mouse infection method, the cost of both manpower and material resources larger, but also need more than 20 days before the survey results can not immediately understand the extent of infection of water can not be generalized in the application of the unit. In recent years, we try sticking precipitation (referred to sticky method) to check the natural water of schistosomiasis
