Figure. . . Phylogenetic tree of near full-length and partial sequences (open reading frame 2) of parvovirus 4 (PARV4), PARV4-like viruses, and Hong Kong virus (HoV) created by using MEGA5.05 (www.megasoftware.net) with the maximum likelihood-method (GTR+G+I) and bootstrap analysis of 1,000 resamplings. Sequence origin was indicated as follows: circle, from humans; square, from chimpanzees; triangle, from red colobus monkeys; and tetragon, from black-and-white colobus monkeys. New sequences from Côte d’Ivoire are shown with filled symbols. P.t.t., Pan troglodytes troglodytes; P.t.v., Pan troglodytes verus; P. badius, Piliocolobus badius; C. polykomos, Colobus polykomos; BHoV, bovine HoV; PHoV, porcine HoV; OHoV, ovine HoV; Eh-BtPV-1, Eidolon helvum parvovirus 1; Gt, genotype of human PARV4. Scale bar indicates nucleotide substitutions per site.
