Characterization of two HPV-3 related papillomaviruses from common warts that are distinct clinically from flat warts or epidermodysplasia verruciformis.
We have recently identified two unusual human papillomavirus (HPV) isolates while engaged in an ongoing study of wart disease in meat handlers and veterinarians. The papillomas from which these two viruses were isolated clinically resembled verruca vulgaris rather than either flat warts or epidermodysplasia verruciformis (EV). These two previously uncharacterized HPVs were molecularly cloned and characterized with respect to known HPVs. The genomes of the two viruses exhibited dramatically different restriction endonuclease cleavage patterns but were found to have significant sequence homology to each other, as well as to HPV-3 and a new virus isolated from a patient with EV. Neither of the two new HPV isolates exhibit detectable sequence homology under stringent conditions of hybridization or share similar restriction endonuclease cleavage patterns with previously characterized HPV types 1,2,4,5,6b, or a previously isolated HPV from meat handlers.
