Genome characterization of a bovine papillomavirus type 5 from cattle in the Amazon region, Brazil.

Abstract

Papillomaviruses are small and complex viruses with circular DNA genome that belongs to the Papillomavirus family, which comprises at least 39 genera. The bovine papillomavirus (BPV) causes an infectious disease that is characterized by chronic and proliferative benign tumors that affect cattle worldwide. In the present work, the full genome sequence of BPV type 5, an Epsilonpapillomavirus, is reported. The genome was recovered from papillomatous lesions excised from cattle raised in the Amazon region, Northern Brazil. The genome comprises 7836 base pairs and exhibits the archetypal organization of the Papillomaviridae. This is of significance for the study of BPV biology, since currently available full BPV genome sequences are scarce. The availability of genomic information of BPVs can provide better understanding of the differences in genetics and biology of papillomaviruses.
