Biogeocoenosis by vegetation of exterminating oncomelania for prevention of schistosomiasis in rural areas

Objective To explore the strategy of eliminating oncomelania and preventing schistosomiasis by vegetation for improving ecological environment in rural areas of China.Methods It was reviewed that oncomelania was intermediate host of schistosome and a role of pathological transmission of schistosomiasis.The mechanism of synusiologic strategy by vegetation of eliminating oncomelania and preventing schistosome was explained.Results It showed that synusiologic strategy of eliminating oncomelania and preventing schistosome improved ecological environment,decreased environmental pollution by chemicals of eliminating oncomelania,cut down costs of eliminating oncomelania.Conclusion Oncomelania is intermediate host of schistosome.It is believed that the strategy will cut out transmission of schistosomiasis,ensure improvement of economy and health service in the countryside.
