Table 2. The number of different HPV types or putative types identified in the 3 pools of HPV consensus PCR amplimers from 326 skin lesion samples. Established (known, sequenced and numbered HPV type); Known putative (known HPV sequence, present in Genbank and different (<90% nt similarity in the L1 gene) from other Established types or Known HPV sequences) and Novel putative (not present in Genbank and different (<90% nt similartity in the L1 gene) from all Established HPV types or HPV sequneces present in Genbank). Pool A) frozen biopsies from 29 SCCs and 31 AKs, pool B) frozen biopsies from 91 KAs and pool C) swab samples from 84 SCCs and 91 AKs, where SCC = squamous cell carcinoma, AK = actinic keratosis and KA = keratoachantoma. *The number of known and novel types detected according to genera is based on the top hit sequence in BLAST.
