| detection and phylogenetic analysis of norovirus in corbicula fluminea in a freshwater river in japan. | to study the molecular epidemiology of noroviruses (novs) in bivalves residing in freshwater rivers, we detected, quantified and phylogenetically analyzed the nov genome in purified concentrates obtained from the gills and digestive diverticula of corbicula fluminea in a freshwater river in gunma prefecture, japan. we detected the nov genome in 35 of the 58 c. fluminea samples. based on our phylogenetic analysis, the nov genome detected in the samples was classified into 4 genotypes (gi/1, gi/2, ... | 2007 | 17895598 |
