Bovine papillomavirus 24: a novel member of the genus Xipapillomavirus detected in the Amazon region.

Bovine papillomaviruses (BPVs) have been described as etiologic agents of cutaneous and mucosal papillomas in cattle. In the present study, we describe a new BPV that was detected in a cutaneous papilloma from a cow. Phylogenetic analysis suggests that this virus belong to the genus Xipapillomavirus, and we refer to it here as BPV type 24 (BPV24). Coinfection with members of the genera Epsilonpapillomavirus and Deltapapillomavirus in a cutaneous papilloma from a different animal was also detected, and the full genomes of these viruses were sequenced. Both papillomas were from cattle within Acre State in the Amazon region of Brazil. The data presented here demonstrate the utility of using high-throughput methods to indentify coinfections and allow the characterization of new genomes.
