The maximum coverage for all nine sequences is 357 nt, though coverage for seven haplotypes is 538 nt. Canarypoxvirus (CNPV) strains are shown in red; Fowlpoxvirus (FWPV) strains are blue. Number of nucleotide substitutions are marked on the line by a solid circle, or shown in parenthesis (when numerous). The continent and avian order of detection, and number of known host species (N = x), are shown below each strain. Note that FWPV-PD1 and PD2 are identical in the 357 nt sequence, but differ at five nt sites in the extended 538 nt sequence (resolution determined only from the extended 538 nt sequence, is indicated by a dotted line). Geographic and host taxonomic information associated with these sequences is based on the extended 538 nt sequence.
