Figure 2. Phylogenetic trees of West Nile Virus (WNV) nucleotide
sequences. Phylograms were constructed with the MEGA program, by using
the Jukes Cantor algorithm and the neighbor-joining method. The percentage
of successful bootstrap replicates is indicated at nodes. The length of
branches is proportional to the number of nucleotide changes (% of divergence).
The strains sequenced in this study are indicated by asterisks (*). A)
