[Role of Oncomelania hupensis in transmission of schistosomiasis japonica].

ABSTRACT

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.
