Title: Two newly identified human papillomavirus types (HPV 40 and 57) isolated from mucosal lesions. Author: de Villiers EM, Hirsch-Behnam A, von Knebel-Doeberitz C, Neumann C, zur Hausen H. Journal: Virology; 1989 Jul; 171(1):248-53. PubMed ID: 2545031. Abstract: 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. HPV 57 DNA was present in an oral wart, a genital condyloma acuminatum, and verrucae vulgares lesions from two immunosuppressed patients.[Abstract] [Full Text] [Related] [New Search]
