Lumpy Jaw

A jaw characterised by painful, ‘wood-hard’ fibrotic induration of the parotid and submandibular regions, arising in a background of dental disease—caries, periodontitis—or extractions, due to cervicofacial actinomyces, the most common form of actinomyces infection

lumpy jaw

see actinomycosis. The etiology in captive macropods is unclear but is probably Fusobacterium spp.

lumpy-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.

lumpy jaw

Infectious disease A jaw characterized by painful, 'wood-hard' fibrotic induration of the parotid and submandibular regions, arising in a background of dental disease–caries, periodontitis, or extractions, due to cervicofacial actinomyces, the most common form of actinomyces infection; LJ in humans is caused by A israeli and others; other findings in cervicofacial actinomycosis include trismus, multiple draining sinus tracts bearing the classic yellow-white sulfur granules, fever, leukocytosis, extension to facial soft tissue, bone and, if untreated, the CNS Treatment Penicillin.
