Caprine Arthritis Encephalitis (Leukoencephalomyelitis of goats, caprine encephalomyelitis)

Caprine arthritis encephalitis (CAE) was first recognized in the early 1970's, and has emerged to be a significant and economically costly disease. The CAE virus (CAEV) is a member of the family Retroviridae, subfamily lentivirus, and hence has gained much attention as the "AIDS" virus of goats . CAEV typically infects dairy goats and is most prevalent in western countries. Caprine arthritis encephalitis has emerged to become one of the five most important diseases of dairy goats in the western hemisphere and such should be perceived as a major threat to the goat industry. CAEV creates a persistent infection which may regress but will invariably worsen with time, and although CAE is detected in a goat it is not automatic grounds for euthanasia. There is no cure and supportive therapy is the only course of action. This includes good nutrition, nursing care, palliative measures and phenylbutazone to decrease discomfort.

Arthritis is the most common form of CAE.
