Fig. 3.

Neighbor-joining phylogenetic tree based on concatenated DNA sequences encoding 4b core protein and DNA polymerase of avipoxviruses (APVs). APV clades A to C and subclades are labeled according to the nomenclature of Gyuranecz et al. [3]. The sequences obtained from Japanese cormorants in this study are indicated in italicized underlined bold face. Both sequences are clustered in subclade A3, which represents APVs of marine birds [3]. All other sequences are indicated as accession number/host species/country/year/clade and subclade number. The bootstrap probabilities, as determined for 1,000 resampling, larger than 900 are given.
