Fig 4.

Unrooted maximum likelihood phylogeny of 83 FCV consensus sequences obtained from the community study and 21 published FCV sequences obtained from GenBank (accession numbers are shown in reference 13). Strains (L1 to L11, W1 to W4, and L plus W) are represented by shaded arcs. For each strain, the JC genetic diversity (%) and, where available, the geographic dispersal (km) and number of calendar months in which it was present are indicated within the box. Published sequences are presented by name, country, and year of origin. Numbers at major nodes are bootstrap values of >800 of 1,000 replicates (expressed as percentages).
