Bayesian analysis of eastern equine encephalitis virus isolates composed of concatenated regions of nonstructural protein 1 (NSP1), NSP2, NSP3, capsid, and envelope 1 genes from different regions of Florida. Bayesian phylogenies were prepared by using the MrBayes program package,19,20 as described in the Materials and Methods. Phylogenies were rooted using the NJ60 sequence. Branch lengths are proportional to distance (the number of nucleotide changes), and the distance scale at the bottom of the tree represents the number of expected substitutions per site. Values indicate the probability for each partition or clade in the tree.
