Maximum likelihood phylogeny of prM/E sequences of Peruvian yellow fever isolates constructed using PAUP*, 4.0b4a (17). Horizontal branch lengths represent genetic divergence, and numbers above the branch lengths denote support for individual clades as determined by nonparametric bootstrap analysis with 1,000 replicates (first value) and Bayesian posterior probabilities (second value). Only the values relevant for the interpretation of results are given. The strains used are listed in Table 1.
