Polyomaviridae - Classification

Classification

The classification of Polyomaviruses is constantly evolving due to the explosion of newly discovered viruses. Previously, the family of Polyomaviridae was divided into three major clades (genetically-related groups) - the SV40 clade, the avian clade, and the murine polyomavirus clade: Recent reclassification by the International Committee on Taxonomy of Viruses (ICTV) recommended dividing the family of Polyomaviridae into three genera :

  • Genus Orthopolyomavirus (type species SV40)
  • Genus Wukipolyomavirus (type species KI polyomavirus)
  • Genus Avipolyomavirus (type species Avian polyomavirus)

Many of the known viruses have not been fully classified or have not yet been officially accepted; hence, the taxonomy of this family is on going.

Genus Orthopolyomavirus (type species SV40):
