Related to lumpy jaw: wooden tongue
A disease primarily of cattle and humans caused by the bacterium Actinomyces bovis in cattle and by A. israelii and Arachnia propionica in humans. These actinomycetes are part of the normal bacterial flora of the mouth and pharynx, but when introduced into tissue they may produce chronic destructive abscesses or granulomas that eventually discharge a viscid pus containing minute yellowish granules (sulfur granules). In humans, the disease commonly affects the cervicofacial area, abdomen, or thorax; in cattle, the lesion is commonly found in the mandible.

Usage notes: nontechnical.
actinomycosis of cows, caused by infection with Actinomyces bovis and not communicable to humans.

lumpy jawInfectious 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. See Actinomycosis.

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