Figure 2. Phylogenetic tree generated from maximum parsimony analysis of genomic sequences of Venezuelan equine encephalitis virus (VEEV) strains 255010 and 254934 and homologous GenBank sequences from the 1962–64 and 1995 VEEV outbreaks, as well as other representative VEE complex alphavirus strains. Numbers indicate bootstrap values for groupings to the right. Enlargement on the lower left shows the 1962–64 and 1995–2000 clades, with numbers indicating nucleotide substitutions accompanying VEEV evolution.
