Phylogenetic analysis of hantaviruses from the Western Hemisphere on the basis of partial A) small and B) medium segments. Novel strains described in this study are indicated in boldface. Depicted phylogenetic reconstructions are based on Bayesian inference conducted in MrBayes (29,30). Posterior probabilities are indicated at relevant nodes. Scale bar indicates nucleotide sequence divergence.
