| [studies on the strain differences of schistosoma japonicum in the mainland of china. ii. susceptibility of mammalian hosts]. | six species of animals were percutaneously exposed to cercariae obtained from pools of naturally infected snails from different isolates of s. japonicum in the mainland of china as shown in tables 1 and 2. our results indicated that with the exception of rat, all animals under study were permissive host though their worm recovery rates varied with different isolates. the mean prepatent period in different host species were 35.0 +/- 0.8 to 36.4 +/- 1.0 days for anhui isolate; 34.5 +/- 1.2 to 36.4 ... | 1990 | 2099256 |
| 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 |
| 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 |
| 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 |
| [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 |
| landscape pattern analysis and bayesian modeling for predicting oncomelania hupensis distribution in eryuan county, people's republic of china. | detailed knowledge of how local landscape patterns influence the distribution of oncomelania hupensis, the intermediate host snail of schistosoma japonicum, might facilitate more effective schistosomiasis control. we selected 12 villages in a mountainous area of eryuan county, yunnan province, people's republic of china, and developed bayesian geostatistical models to explore heterogeneities of landscape composition in relation to distribution of o. hupensis. the best-fitting spatio-temporal mod ... | 2009 | 19706906 |
