The name papovavirus is derived from the first two letters of the three prototypes: rabbit papilloma virus, polyoma virus and siman vacuolating virus 40 (SV 40).
The capsid of the papilloma polyoma group consists of 72 morphological units assembled from 420 structure units (T=7).
The surface lattice is skewed and the skewing may be right handed or left handed.
