- bovine p. stomatitis — a benign stomatitis caused by a poxvirus in the genus Parapoxvirus. Lesions occur in young cattle and are characterized by round papules that develop a roughened center which expands and may merge with other adjacent lesions to give a network effect. The lesions are on the buccal mucosa and the adjoining skin of the muzzle and occasionally esophagus and forestomachs.
