本实验的目的在于用小白鼠感染方法来测验血吸虫病流行区河水的感染性,在不同季节有无变化。掌握这种变化对部队预防血吸虫病将提供很重要的资料,以便因时制宜地进行预防工作。由于各种困难,如小白鼠不能经受冬季冷水浸泡等,我们未能对全年的季节消长情况进行观察。调查地点及方法调查地点选择在浙江江山县清湖乡七里桥至毛墩村的一段河道(位于某部驻地附近)。该地是一严重的血吸虫病流行区,居民感染率为54.1%。进行小白鼠感染的河道南北向,河宽10-20公尺,水流缓
The purpose of this experiment is to test the infectivity of schistosomiasis endemic areas using the mouse infection method, with or without changes in different seasons. Grasp of such changes will provide important information on troop prevention of schistosomiasis in order to prevent epidemics as appropriate. Due to various difficulties such as the inability of mice to withstand winter cold water immersion, we have not been able to observe the seasonal fluctuations throughout the year. Survey site and method Survey site Select a section of river (located near a certain station) in Qiaoliqiao to Mao Dun Village, Qinghu Township, Jiangshan County, Zhejiang Province. The area is a serious endemic area of schistosomiasis, with a resident infection rate of 54.1%. River infection of mice north-south, 10-20 meters wide river, slow water flow
