Fig 2. Consensus maximum-likelihood tree of North American WNV ORFs, 1999–2012 (n = 870).

Fig 2

WNV genotypes are color-coded as NY99 (black), INTermediate (orange), WN02 (blue), SW/WN03 (purple) and cluster MW/WN06 (red). All WNV sequences derived from this study are labeled by black diamonds, and Nodes 1 to 6 containing these sequences are highlighted in green and shown in detail. Taxon names correspond to GenBank accession numbers and years of collection. Node-specific amino acid substitutions are shown for each node (see also S4 Table). For each node, states shown in red in the adjacent U.S. map are those from which strains have been isolated.
