| genotyping natural infections of schistosoma mansoni in biomphalaria alexandrina from damietta, egypt, with comparisons to natural snail infections from kenya. | the distribution of schistosoma genotypes among individuals in snail populations provides insights regarding the dynamics of transmission and compatibility between schistosome and snail hosts. a survey of biomphalaria alexandrina from damietta (nile delta, egypt), an area subjected to persistent schistosomiasis control efforts, provided only 17 snails infected with schistosoma mansoni (6.1% overall prevalence), each shown by microsatellite analysis to have a single genotype infection. by contras ... | 2010 | 21348627 |
| tissue responses exhibited by biomphalaria alexandrina snails from different egyptian localities following schistosoma mansoni exposure. | snails' susceptibilities to infection with schistosoma mansoni were determined through observation of infection rates, total cercarial production and tissue responses of the first generation (f1) of biomphalaria alexandrina snails, originally collected from different egyptian governorates (giza, fayoum, kafr el-sheikh, ismailia and damietta) and responses were compared between groups. the emergence of cercariae for a 3-month period and the calculation of survival and infection rates, in control ... | 2011 | 21295031 |
| the relationship between genetic variability and the susceptibility of biomphalaria alexandrina snails to schistosoma mansoni infection. | in the present study, biomphalaria snails collected from five egyptian governorates (giza, fayoum, kafr el-sheikh, ismailia and damietta), as well as reference control biomphalaria alexandrina snails from the schistosome biological supply center (sbsc) (theodor bilharz research institute, egypt), were subjected to species-specific polymerase chain reaction (pcr) assays to identify the collected species. all of the collected snails were found to be b. alexandrina and there was no evidence of the ... | 2012 | 22510827 |
