Abstract
    We identified sequences from two distantly related papillomaviruses in genital warts from two Burmeister's porpoises, including a PV antigen-positive specimen, and characterized Phocoena spinipinnis papillomavirus type 1 (PsPV-1). The PsPV-1 genome comprises 7879 nt and presents unusual features. It lacks an E7, an E8 and a bona fide E5 open reading frame (ORF) and has a large E6 ORF. PsPV-1 L1 ORF showed the highest percentage of nucleotide identity (54–55?%) with human papillomavirus type 5, bovine papillomavirus type 3 (BPV-3) and Tursiops truncatus papillomavirus type 2 (TtPV-2). This warrants the classification of PsPV-1 as the prototype of the genus Omikronpapillomavirus. PsPV-1 clustered with TtPV-2 in the E6 and E1E2 phylogenetic trees and with TtPV-2 and BPV-3 in the L2L1 tree. This supports the hypothesis that PV evolution may not be monophyletic across all genes.
