湖北钉螺在日本血吸虫病传播中的作用

Role of Oncomelania hupensis in transmission of schistosomiasis japonica

湖北钉螺是日本血吸虫的唯一中间宿主,其生态特征及与血吸虫的相容性在血吸虫病传播中起着极其重要的作用,加强该类研究对防控血吸虫病具有重要意义。本文对温度、湿度、植被、土壤等影响钉螺生存的生态因子和钉螺密度、钉螺异地生长繁殖,以及钉螺与血吸虫相容性方面的研究进行了综述。

Oncomelania hupensis is the only intermediate host of Schistosomajaponicum, and its ecological characteristics and compatibility with Schistosoma which have a great significance to the schistosomiasis control, play a very important role in the transmission of schistosomiasis. This paper reviews the researches on the ecological factors which effect the survive of Oncomelania snails such as temperature, humidity, vegetation, and soil, as well as the snail density, the development and breeding of snails in the foreign habitats, and its compatibility with Schistosoma.
