Identification of an immunologically distinct papillomavirus from lesions of epidermodysplasia verruciformis.
Virions isolated from warts of 2 siblings with epidermodysplasia verruciformis (EV), a rare disease characterized by the lifelong growth of warty skin tumors containing papova-like virions, were compared to isolates of human papillomavirus (HPV) from 3 pools of plantar and common hand warts. The length of relaxed, circular (form II) molecules of EV virion DNA approximated the length of HPV DNA but was 3.3% longer. Antisera prepared in rabbits against the 3 HPV pools coated and aggregated HPV in  immune electron microscopy (IEM) tests but did not react with EV virions. These antisera reacted at high titers in complement fixation (CF) tests with HPV and reacted only weakly in CF tests with EV virions. Rabbit antisera to EV virions coated and aggregated EV virions but reacted only weakly or not at all with HPV virions in IEM tests. These sera reacted in CF with EV virions only. The data indicated that virions from the EV patients represent an immunologically distinct papillomavirus.
