(mī-sĕ-tō′mă, mī-sĕ-tō′măt-ā) pl. mycetomas, mycetomata [mycet- + -oma] A syndrome caused by a variety of aerobic actinomycetes and fungi. It is characterized by swelling and suppuration of subcutaneous tissues and formation of sinus tracts, with granules present in the pus draining from the tracts. These tracts usually appear on the foot or leg. SEE: actinomycetoma; eumycetoma.
TREATMENT: Sulfones, trimethoprim and sulfamethoxazole, or sulfonamides may benefit lesions caused by actinomycetes. If lesions are due to fungi, there is no specific therapy.

(mī″kō-bak-tir′ē-ŭm) [myco- + bacterium] A genus of slender, acid-fast, nonmotile, non–spore-forming bacilli of the family Mycobacteriaceae, which includes the causative agents of tuberculosis and leprosy. Species include M. africanum, M. avium intracellulare, M. bovis, M. chelonei, M. fortuitum, M. gastri, M. gordonae, M. kansasii, M. marinum, M. scrofulaceum, M. terrae, M. triviale, M. smegmatis, and M. xenopi.
M. bovis The causative species of tuberculosis in cows and, less commonly, in humans.
M. kansasii A causative species of tuberculosis- like pulmonary disease in humans.
M. leprae The causative species of leprosy.
M. marinum An atypical mycobacterium that thrives in water and produces skin infection resembling sporotrichosis. It is the cause of swimming pool granuloma.
nontuberculous M. ABBR: NTM. Any mycobacterium that does not cause tuberculosis. There are four main classes. Three of these groups grow more slowly than M. tuberculosis and one group grows more rapidly. These organisms may cause various skin, lung, or other conditions or they may be harmless.
M. tuberculosis The causative agent of tuberculosis in humans. SEE: tuberculosis.
M. ulcerans A causative agent of infections of the skin and the underlying soft tissues. It is a common cause of illness in tropical and subtropical Africa and South America, where it is responsible for Buruli ulcer. It is thought to be the third most common disease-causing mycobacterium (after M. tuberculosis and M. leprae) in humans.
Mycobacterium abscessus complex
