Bovine herpesvirus 2
（重定向自Bovine mammillitis）
Bovine herpesvirus 2 (BoHV2) is a virus of the family Herpesviridae that causes two diseases in cattle, bovine mammillitis and pseudo-lumpy skin disease. BoHV2 is similar in structure to human herpes simplex virus.
Pseudo-lumpy skin disease was originally discovered in South Africa where a similar but more serious disease caused by a poxvirus, lumpy skin disease, is also prevalent. Symptoms include fever and skin nodules on the face, back, and perineum. The disease heals within a few weeks. Bovine mammillitis is characterized by lesions restricted to the teats and udder. BoHV-2 probably spreads through an arthropod vector, but can also be spread through milkers and milking machines.
