|Description:||From the “Illustrated Manual for the Recognition and Diagnosis of Certain Animal Diseases”, published in 1982, by the Mexico-United States Commission for the Prevention of Foot and Mouth Disease, this photograph depicts a close-up the lower teeth and gums of a bovine, which displayed gingival lesions due to a case of bovine papular stomatitis (BPS).|
Caused by a virus belonging to the family Poxviridae, and the genus Parapoxvirus, “BPS is a widely-distributed disease, which produces popular, and occasionally erosive lesions on the muzzle and buccal mucous membranes of young cattle. Though primarily a disease of calves, the virus can affect humans, also causing skin lesions."
"Clinically, symptoms may include a transient anorexia or a slight fever, but in most instances the disease goes unnoticed, unless a careful examination of the mouth is [performed]. Lesions are usually confined to the muzzle, nostrils, and the buccal mucosa. The vast majority of infected animals survive without serious harm, and are therefore, not subjected to necropsy.”
