Felis domesticus papillomavirus, isolated from a skin lesion, is related to canine oral papillomavirus and contains a 1.3 kb non-coding region between the E2 and L2 open reading frames

We have characterized the complete genome (8300 bp) of an isolate of Felis domesticus papillomavirus (FdPV) from a domestic cat with cutaneous papillomatosis. A BLAST homology search using the nucleotide sequence of the L1 open reading frame demonstrated that the FdPV genome was most closely related to canine oral papillomavirus (COPV). A 384 bp non-coding region (NCR) was found between the end of L1 and the beginning of E6, and a 1.3 kbp NCR was located between the end of E2 and the beginning of L2. Phylogenetic analysis placed FdPV in the E3 clade with COPV. Both viruses contain the atypical second NCR, which has no homology with sequences in existing databases.
