Abstract

Papillomavirus oncogenesis as a benign process, clinically diagnosed as papillomatosis, is common in small domestic animals, in particular among cats and dogs, but in the nosological structure of neoplasms has a different ratio depending on the species. Recent data indicate the provocation of precancerous and neoplastic lesions in domestic species by the papillomatosis virus. Clinically, oncogenesis is associated with lesions of the skin and mucous membranes, which is determined by the tropicity of the virus, since the papillomavirus replication cycle is closely related to the differentiation of cells of the multilayer squamous epithelium, and in accordance with the morphological classification provokes the development of epithelial tumors without specific localization. The following neoplasms were identified in the structure of tumors of epithelial origin in dogs and cats: papilloma, squamous cell carcinoma and basal cell carcinoma. In statistical studies during the study period, organ-specific tumors in dogs amounted to 23.85%, in cats 12.5%. The concept of infectious oncology is used, which includes and combines the basic principles of infectious and oncological processes. Bibliographic analysis revealed the associativity of papillomavirus infection with specific neoplasms, depending on the taxonomy of the virus and the type of animal.
