New generic primer system targeting mucosal/genital and cutaneous human papillomaviruses leads to the characterization of HPV 115, a novel Beta-papillomavirus species 3.
We explored the cutaneotropic HPV genetic diversity in 71 subjects from Argentina. New generic primers (CUT) targeting 88 mucosal/cutaneous HPV were designed and compared to FAP primers. Overall, 69 different HPV types/putative types were identified, being 17 of them novel putative types. Phylogenetic analysis of partial L1 sequences grouped 2 novel putative types in the Beta-PV, 14 in the Gamma-PV and 1 in the Mu-PV genera. CUT primers showed broader capacity than FAP primers in detecting different genera/species and novel putative types (p<0.01). Using overlapping PCR, the full-length genome of a Beta-PV putative type was amplified and cloned. The new virus, designated HPV 115, encodes five early genes and two late genes. Phylogenetic analysis indicated HPV 115 as the most divergent type within the genus Beta-PV species 3. This report is the first providing data on cutaneous HPVs circulating in South America and expands our knowledge of the Papillomaviridae family.
