Bovine papular stomatitis (BPS) is a zoonotic viral disease caused by infection with bovine papular stomatitis virus (BPSV). BPSV is a member of the Parapoxvirus genus within the Poxviridae family. BPS primarily affects young cattle. It is characterized by the development of small red-brown colored papules approximately 0.5 cm in diameter on the muzzle, nostrils, dental pad and buccal mucosa of the cow. The lesions are slightly elevated, roughened and horseshoe shaped. Usually multiple cattle from the same herd will show clinical signs of infection.
