Distinguishing features

This genus contains viruses, which are detected on the skin (human polyomaviruses 6 and 7) and in the gastrointestinal tract (human polyomavirus 10 (MW polyomavirus); human polyomavirus 11 (STL polyomavirus)).

Species demarcation criteria

1. Sufficient information on the natural host
2. Observed genetic distance from a member of the most closely related species is >15% for the LTAg coding sequence
3. When two polyomaviruses exhibit <15% observed genetic distance, biological properties may be of additional critical importance (e.g. host specificity, disease association, tissue tropism, etc.)
