title: Molecular cloning and characterization of the DNAs of human papillomaviruses 19, 20, and 25 from a patient with epidermodysplasia verruciformis.
abstract: Five human papillomavirus (HPV) DNAs from lesions of an epidermodysplasia verruciformis patient were cloned in lambda L 47: DNA of HPV 5, which predominated in the carcinoma; DNA of a variant type of HPV 8, which was not detected in the carcinoma DNA by Southern blot hybridization but only by cloning; and DNAs of three papillomaviruses that were isolated from warts. Southern blot and liquid phase DNA-DNA hybridization under stringent conditions showed that the three viruses from warts were new types, which we named HPVs 19, 20, and 25. These viruses cross-hybridized between 3 and 29% among themselves and with HPVs 5 and 8. After physical mapping with several restriction enzymes, the colinear genomes were aligned with HPV 8 DNA to define early and late regions. HPVs 8, 19, and 25 shared homology in different parts of their genomes.
