Phylogenetic analysis of GII norovirus based on the partial nucleotide sequences of the viral polymerase (a) and capsid regions (b). The NoV strains detected in this study are indicated by coloured dots. References NoV genotypes are labelled according to GenBank with their respective accession numbers. The trees were constructed in MEGA 6.0 through the maximum likelihood method using the Kimura 2-parameter model. The bootstrap values (1000 replicates) are indicated in the phylogenetic tree, and values less than 70% are not represented
