Abstract: During the 2008-2009 rotavirus season, 10 G3P[6] rotavirus strains were isolated for the first time in Belgium, while an outbreak of G2P[6] strains occurred in the USA in 2005-2006. Partial sequencing of the 11 genome segments of the 10 Belgian G3P[6] strains revealed a clonal origin. Two of these strains, and a G2P[6] strain representative of the American outbreak, were selected and sequenced completely to analyze their evolutionary relationships. Genetic analysis revealed that all strains possessed a DS-1-like genotype constellation. The 2 Belgian G3P[6] strains showed >99% sequence identity at the nucleotide level and the American G2P[6] strain was phylogenetically closely related to the Belgian P[6] strains. These data suggest that reassortment(s) involving VP7 occurred recently, and that the prevalence of DS-1-like P[6] rotavirus strains need to be closely monitored because the currently licensed RVA vaccines contain neither the P[6] genotype nor strains with a complete human DS-1 genotype constellation.
