Figure 2. Neighbor-joining phylogenetic tree based on complete genome sequences of West Nile virus strains. Strain TM171-03 is indicated in bold text. The topology of maximum parsimony and maximum likelihood trees was essentially identical. Bayesian analysis also confirmed the close relationship between TM171-03 and NY00-grouse3282 sequences (data not shown). Bootstrap values are shown for major branches (500 replicates). GenBank accession numbers for sequences used to construct the tree are indicated on the branches.
