Abstract

The Polyomaviridae Study Group of the International Committee on Taxonomy of Viruses (ICTV) has recommended several taxonomical revisions, as follows: The family Polyomaviridae, which is currently constituted as a single genus (Polyomavirus), will be comprised of three genera: two containing mammalian viruses and one containing avian viruses. The two mammalian genera will be designated Orthopolyomavirus and Wukipolyomavirus, and the avian genus will be named Avipolyomavirus. These genera will be created by the redistribution of species from the current single genus (Polyomavirus) and by the inclusion of several new species. In addition, the names of several species will be changed to reflect current usage.

Fig. 1
Phylogenetic relationships among polyomaviruses based on whole genomic nucleotide sequences. MacVector software was used to perform ClustalW alignments of members of the 25 recognized polyomavirus species. The tree was built by neighbor joining using the Kimura 2-parameter distance model. FigTree and Inkscape software were used for graphic display of the tree. Data on the viruses, including GenBank accession numbers of the genome sequences, are presented in Table 1. Assignment of the viruses to the newly created genera is indicated by shaded ovals

Fig. 2
Phylogenetic relationship among polyomaviruses based on partial nucleotide sequences. The early region encoding the large T antigen (including introns) (A) and the late region spanning the VP2 and VP1 open reading frames (B) are compared separately. Bandicoot papillomatosis carcinomatosis virus 1 and 2 (BPCV1 and BPCV2; GenBank accession numbers NC_010107 and NC_010817) have been included in (A). The method for calculation of the tree and the labeling of the branches is identical to that in Fig. 1
