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 view of a bovine teat, upon which you’ll note lesions with the appearance of hematomas, due to a case of bovine herpes dermopathic (BHD) disease.

“BHD disease is made up of a group of syndromes characterized by pyrexia and the formation of cutaneous lesions. BHD is caused by a number of herpes viruses that are similar in their biological, immunological, and physiochemical characteristics.
“The incubation period for BHD is 1 – 2 weeks. Fever of several days duration precedes the formation of cutaneous nodules, which first appear as round, then flatten later on, becoming exudative and covered by a scab. When the scab falls off, the underlying skin is hairless, though normal. Bovine mammillitis lesions are chiefly restricted to the teats and udder skin, and tend to become ulcerative. A large proportion of cattle herds in enzootic areas develop neutralizing antibodies without having noticeable disease signs or lesions.”
