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 image depicts a close view of a sheep’s muzzle and lips revealing the presence of maculopapular lesions around the mouth and nares, due to a sheep pox (SP) infection. Note that some of the papules had become confluent, which means that they had run together.
“SP is a highly contagious viral disease of sheep characterized by erythematous eruptions on the skin. Early in the course of the disease, SP lesions are papular, but later progress to pustular eruptions. When the lesions are generalized, they may be associated with hemorrhagic inflammation of the respiratory and gastrointestinal mucosae, as well as a high mortality rate.” SP is a member of the family, Poxviridae, and the genus, Capripoxvirus.
