Detection of human rotavirus G9P[8] strains circulating in Argentina: phylogenetic analysis of VP7 and NSP4 genes.
During the surveillance of rotavirus strains that were circulating in Argentinean children from 2000 to 2004, seven rotaviruses were detected bearing the genotype combination G9P[8]. The molecular characterization of the VP7 and NSP4 genes and the RNA migration patterns support the hypothesis that rotaviruses G9 could have been reintroduced into Argentina as a novel G9P[8] strain, rather than represent VP7 gene reassortants from G9P[6] strains that had been circulating previously in this country.
