development and effects of schistosoma japonicum (trematoda) on its intermediate host, oncomelania hupensis (gastropoda).
background: trematodes belonging to the genus schistosoma cause schistosomiasis. the relationship between schistosomes and their intermediate hosts varies among snails. this study investigated the effects of s. japonicum on its snail host, oncomelania hupensis, and cercarial release rythmicity of s. japonicum and the effects of light on it. methods: : seven groups of o. hupensis (n = 40 each) w...
متن کاملComparative Phylogenetic Studies on Schistosoma japonicum and Its Snail Intermediate Host Oncomelania hupensis: Origins, Dispersal and Coevolution
BACKGROUND Schistosoma japonicum causes major public health problems in China and the Philippines; this parasite, which is transmitted by freshwater snails of the species Oncomelania hupensis, causes the disease intestinal schistosomiasis in humans and cattle. Researchers working on Schistosoma in Africa have described the relationship between the parasites and their snail intermediate hosts as...

متن کاملIsolation and Characterization of 15 New Microsatellite Markers in Oncomelania hupensis, the Snail Intermediate Host of Schistosoma japonicum in Mainland China
Oncomelania hupensis is the unique intermediate host of Schistosoma japonicum, which plays a key role during the transmission of schistosomiasis. It is mainly found in the Yangtze River valley and mountains or hills in southwest China. In this paper, we described 15 new microsatellite makers in O. hupensis. Polymorphism of each locus was assessed in 80 individuals from four wild populations (n ...
متن کاملMolluscicidal activities of medicinal plants from eastern China against Oncomelania hupensis, the intermediate host of Schistosoma japonicum
In a search for natural products that could be used to control schistosomiasis, nineteen extracts of eleven medicinal plants from eastern China have been tested for molluscicidal activity against snail Oncomelania hupensis. The n-butanol fraction of the fresh leaf from Buddleja lindleyana Fortune, Buddlejaceae, showed significant activity against the snails. Statistical analysis revealed that t...
