| compatibility between oncomelania hupensis and different isolates of schistosoma japonicum in china. | oncomelania hupensis from six localities were used for infection with different isolates of schistosoma japonicum in the mainland of china, ie anhui in the east, hubei in the center, guangxi in the south, sichuan in the west, yunnan in the southwest and fujian in the southeast. snails from anhui and hubei were readily infected with the local isolate of s. japonicum and cross infection also took place readily between the snails and the schistosomes from these two places. snails from sichuan and y ... | 1991 | 1948286 |
| 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 |
| [studies on the strain differences of schistosoma japonicum in the mainland of china. i. compatibility between schistosomes and their snail hosts]. | oncomelania hupensis hupensis from six localities were used in this study, i.e. guichi of anhui in the east, jianli of hubei in the middle, guiping of guangxi in the south, tianquan of sichuan and eryuan of yunnan in the southwest and fuqing of fujian in the southeast. snails from each locality were individually cross-exposed to 20 miracidia of the different isolates of s. japonicum from the above-named places, with the exception of fujian province where no snail could be found naturally infecte ... | 1990 | 2208632 |
