| epidemiology of schistosoma japonicum in china: morbidity and strategies for control in the dongting lake region. | dongting lake, covering a very large surface water area of 2691km(2), is located in hunan province in the southern part of the people's republic of china. it is the second-largest freshwater lake in china and plays an important role in regulating the amount of water in the yangtze river, china's longest river. the annual water level of the lake changes by as much as 15m, rising in summer and falling in winter. asian schistosomiasis has been endemic in the dongting lake region for centuries and i ... | 2000 | 10719120 |
| oncomelania hupensis (gastropoda: rissooidea) in eastern china: molecular phylogeny, population structure, and ecology. | the rissooidean snail genus oncomelania is of medical interest as various taxa are hosts for the human blood fluke schistosoma and the lung fluke paragonimus; because of close co-evolved host-parasite-relationships, snail diversity may reflect parasite diversity. there is a considerable amount of confusion regarding the identity of smooth- and ribbed-shelled populations of oncomelania hupensis in eastern china. we therefore studied the genetic variation, population structure, phylogenetic relati ... | 2000 | 11080513 |

| landscape genetics: the correlation of spatial and genetic distances of oncomelania hupensis, the intermediate host snail of schistosoma japonicum in mainland china. | two internal transcribed spacer (its1 and its2) sequences of the non-coding region of the rdna and a 16s rna gene fragment of the mtdna of oncomelania hupensis, the intermediate host snail of schistosoma japonicum in mainland china, have been investigated with a view to illustrate the influence of the environment on genetic differentiation. thirteen populations of o. hupensis snails, representing four types of ecological settings, were collected to compare genetic and spatial distances. the leng ... | 2009 | 19440964 |
| distinct genetic diversity of oncomelania hupensis, intermediate host of schistosoma japonicum in mainland china as revealed by its sequences. | oncomelania hupensis is the unique intermediate host of schistosoma japonicum, which causes schistosomiasis endemic in the far east, and especially in mainland china. o. hupensis largely determines the parasite's geographical range. how o. hupensis's genetic diversity is distributed geographically in mainland china has never been well examined with dna sequence data. | 2010 | 20209150 |
