Figure 1.

Phylogenetic tree constructed using partial VP1 gene sequences of chimpanzee polyomaviruses. Grey shading indicates genogroups described in the text, and isolates used for complete genome sequencing are in bold. The published ChPyV VP1 sequence (AY691138) is included in the tree. Sequence alignments were made by using MacVector version 10.6. Phylogenetic analysis was performed by the Neighbor-Joining method as implemented in MEGA version 4 [25]. Bootstrap values (as % of 1000 re-samplings) are indicated. Bar, 0.01 nucleotide replacements per site. First three letters of name indicate subspecies: Ptv, Pan troglodytes verus; Ptt, P.t. troglodytes; Pts, P.t. schweinfurthii. [EMBL: FR692245-FR692275].
