Proposed categorization of GB viruses.Maximum likelihood tree (Tamura 3-parameter nucleotide model and gamma distribution, T92 + G) depicting phylogenetic relationship of Human Pegiviruses with other main members of Flaviviridea family. The phylogenetic tree was constructed based on the complete coding sequence (CDS) of these viruses. The values at the tree branches are the bootstrap support values calculated from 1000 replicates. Scale bar indicates an evolutionary distance of 0.5 substitutions per position in the sequence. GB virus type A, B, C, D (GBV-A, GBV-B, GBV-C, GBV-D), simian Pegivirus(SPgV), human Pegivirus(HPgV), Bat Pegivirus(BPgV), CPZ: chimpanzees
