• l. disease — see lumpy-skin disease (below).
• l. jaw — see actinomycosis. The etiology in captive macropods is unclear but is probably Fusobacterium spp.
• l.-skin disease — there are two distinct lumpy-skin diseases of cattle with a similar clinical syndrome, in which there is a sudden appearance of cutaneous nodules on all parts of the body. Some of the lesions may become necrotic and slough, but most just subside. The more acute and systemic of the two diseases is caused by the ‘Neethling’ poxvirus. The milder form is caused by the ‘Allerton’ herpesvirus, which appears to be identical to the virus of bovine ulcerative mammillitis (bovine herpesvirus 2). Called also knopvelsiekte.
• l. wool — see mycotic dermatitis.
