Fig. 2From: Genetic characterization of norovirus GII.4 variants circulating in Canada using a metagenomic techniquePhylogenetic analysis of the full-length genome sequences. A phylogenetic tree was constructed using certain full-length genome sequences obtained in this study and several full-length sequences from different geographical regions using the Maximum Likelihood method. Sequences in red are isolated from Ontario, blue for Nova Scotia, green from Newfoundland. The recombinant sequence is shown in boldBack to article page
