Fig. 1From: Genetic characterization of norovirus GII.4 variants circulating in Canada using a metagenomic techniquePhylogenetic analysis of individual ORFs. Consensus sequences obtained in this study along with certain full-length Canadian sequences and reference sequences were aligned and phylogenetic trees were constructed for ORF1 (a), ORF2 (b) and ORF3 (c) using the Maximum Likelihood method. The robustness of the phylogeny was assessed through bootstrap analysis of 1000 pseudo-replicates. Sequences in brown are isolated from Ontario, orange from Alberta, blue for Nova Scotia, green from Newfoundland and Labrador. The recombinant sequence is shown in bold. The sequences generated in this study are italicizedBack to article page
