DNA from two novel HPV genotypes, HPV-150 and HPV-151, isolated from hair follicles of immuno-competent individuals, was fully cloned, sequenced and characterized. The complete genomes of HPV-150 and HPV-151 are 7,436-bp and 7,386-bp in length, respectively. Both contain genes for at least six proteins, namely E6, E7, E1, E2, L2, L1, as well as a non-coding(More)
The DNA genome of a novel HPV genotype, HPV-125, isolated from a hand wart of an immuno-competent 19-year old male was fully cloned, sequenced and characterized. The full genome of HPV-125 is 7,809-bp in length with a GC content of 46.4%. By comparing the nucleotide sequence of the complete L1 gene, HPV-125 is phylogenetically placed within cutaneotrophic(More)
Human papillomaviruses (HPVs) were detected in 69 (43.7%) of 158 and in 7 (4.5%) of 155 anogenital hairs obtained from 53 patients with genital warts (GWs) and from 53 age-matched healthy control subjects, respectively. At least 1 hair sample was positive for 69.8% of patients and for 13.2% of control subjects. For patients, HPV was detected in 64.2%,(More)
Association between verrucous carcinoma (VC) of the head and neck and human papillomaviruses (HPV) is highly controversial. Previous prevalence studies focused mostly on α-PV, while little is known about other PV genera. Our aim was to investigate the prevalence of a broad spectrum of HPV in VC of the head and neck using sensitive and specific molecular(More)
Gammapapillomavirus (Gamma-PV) is a diverse and rapidly expanding PV-genus, currently consisting of 76 fully characterized human papillomavirus (HPV) types. In this study, DNA genomes of two novel HPV types, HPV179 and HPV184, obtained from two distinct facial verrucae vulgares specimens of a 64 year-old renal-transplant recipient, were fully cloned,(More)
BACKGROUND The aims of the study were to review single-institution experiences with sinonasal inverted papilloma associated with squamous cell carcinoma (IP/SCC), to analyze the presence of human papillomavirus (HPV) and to evaluate the role of radiotherapy. PATIENTS AND METHODS Five patients with IP/SCC were identified in the prospective institutional(More)
BACKGROUND Betapapillomaviruses (β-PV) are etiologically associated with epidermodysplasia verruciformis and a proportion of skin precancerous lesions and cancer, mainly in immunocompromised individuals. OBJECTIVES The prevalence and persistence of anal β-PV infection and β-PV type distribution were determined in a cohort of men who have sex with men(More)
We report the cloning and characterization of a novel human papillomavirus (HPV), now officially recognized as HPV-174, isolated from a cutaneous squamous cell carcinoma. HPV-174 has a genome organization characteristic of cutaneous HPV types, clusters to the genus Betapapillomavirus, species β2, and is most closely related to HPV-145.
The novel human papillomavirus type 199 (HPV199) was initially identified in a nasopharyngeal swab sample obtained from a 25 year-old immunocompetent male. The complete genome of HPV199 is 7,184 bp in length with a GC content of 36.5%. Comparative genomic characterization of HPV199 and its closest relatives showed the classical genomic organization of(More)
