Figure 2

Maximum-likelihood phylogenetic analysis of rare norovirus GIV isolated during foodborne outbreak, Wisconsin, USA (red text), and reference strains. A) Partial polymerase gene (762 nt); B) complete capsid (VP1) gene (554 aa). Bootstrap support for 500 replicates is indicated on branches. For polymerase analysis, evolutionary distances were inferred by the Tamura-Nei model. For VP1 analysis, evolutionary distances were inferred by using the Jones-Taylor-Thornton matrix-based model. Reference strains are represented by type and GenBank accession number. Scale bar in panel A indicates nucleotide substitutions per site, and scale bar in panel B indicates amino acid substitutions per site.
