Nucleotide sequence of human papillomavirus (HPV) type 41: an unusual HPV type without a typical E2 binding site consensus sequence.

The complete nucleotide sequence of human papillomavirus type 41 (HPV-41) has been determined. HPV-41 was originally isolated from a facial wart, but its DNA has subsequently been detected in some skin carcinomas and premalignant keratoses (Grimmel et al., Int.

A comparative sequence analysis of two human papillomavirus (HPV) types 2a and 57.

HPV 2a is commonly associated with verrucae vulgares, whereas HPV 57 was detected in mucosal lesions of the maxillary sinus and the genital tract, as well as in cutaneous lesions. The complete DNA sequences of HPV 2a and HPV 57 were determined. The HPV 2a genome consists of 7860 base pairs and the HPV 57 genome contains 7861 base pairs.

Two newly identified human papillomavirus types (HPV 40 and 57) isolated from mucosal lesions.

Two new papillomaviruses, HPV 40 and HPV 57, were isolated from a PIN lesion and an inverted papilloma of the maxillary sinus, respectively. HPV 40 showed a 13% homology to HPV 7 by reassociation kinetics and HPV 57 showed a 17% homology to HPV 2 and 25% homology to HPV 27. Hybridization of the DNA of these papillomaviruses to a wide variety of different tumor biopsies revealed that HPV 40 was present in a few genital condylomata acuminata as well as in bowenoid lesions.
