High Genotypic Diversity, Putative New Types and Intra-Genotype Variants of Bovine Papillomavirus in Northeast Brazil.

Bovine papillomavirus (BPV) can cause damage to the epithelial and mucosal tissue and currently presents 28 known types. Not all BPV types are associated with the development of cancer in cattle. Studies have shown that variants of human papillomavirus types can present different pathogenic profiles.

Molecular characterization of Canis familiaris oral papillomavirus 1 identified in naturally infected dogs from Northeast Brazil.

Background: Canine papillomavirus (CPV) has 20 described types associated with papillomas or squamous cell carcinoma (SCC). Knowledge about CPV diversity is scarce. Studies on papillomaviruses that infect other hosts show substantial diversity with some types and variants being associated with cancer.
