Figure 1

Phylogenetic tree based on partial nucleotide sequences of norovirus GII.4 ORF1 and ORF2. Seven samples of GII.Pe/GII.4 Sydney 2012 genotype in this study were compared to other representative GII.4 reference strains. The sequences of the region comprising nucleotide 4331-6660 were compared. The scale bar represents genetic distance (expressed as nucleotide substitutions per site).
