Equine papillomavirus is a virus that infects horses, leading to the development of benign growths known as papillomas or warts, typically on the skin or mucous membranes. These viruses belong to the Papillomaviridae family and are species-specific, with several types identified in horses. Papillomavirus infections are generally self-limiting, but in some cases, they can persist or lead to more severe conditions such as sarcoids, which are locally invasive skin tumors. This page compiles peer-reviewed research studies and scholarly articles that explore the biology, transmission, clinical presentation, and potential treatments of papillomavirus infections in horses.

This is a study investigating the equus caballus papillomavirus type 2 (EcPV2) infection state as well as the EMT process and the tumor microenvironment in vulvo-vaginal preneoplastic/ benign (8/22) or malignant (14/22) epithelial lesions in mares. To do this, histopathological, immunohistochemical, transcriptomic, hybridization, and correlation analyses were carried out. Immunohistochemistry quantification showed tha...
