Mycobacterium ulcerans(redirected from M. ulcerans)
a bacterial species causing Buruli ulcers in humans; transmissible from soil, usually after an injury, and possibly by an insect vector.
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 ulceransAn organism, of the same genus as those causing TUBERCULOSIS and HANSEN'S DISEASE (leprosy), that causes gross and extensive necrotic lesions called Buruli ulcer in affected people in endemic areas, mainly in West Africa.
the only genus in the family Mycobacteriaceae of bacteria; slender acid-fast rods which may be straight or slightly curved. They may produce filaments or cocci. The most serious disease caused by members of this genus is tuberculosis. M. fortuitum, M. chelonea, M. marinum are listed as causes of piscine tuberculosis. Other species, including M. aquae, M. kansasii and M. scrofulaceum, may occasionally cause disease in a number of different species.
found mostly in birds but occasionally also in other animals and in humans. The tubercle bacillus of birds, it causes avian tuberculosis.
Mycobacterium avium subsp. paratuberculosis
causes Johne's disease in cattle, sheep, goats, deer and camelids. Previously called M. johnei and M. paratuberculosis.
complex see M. intracellulare (below).
the tubercle bacillus of the bovine, it causes tuberculosis in many animal species and humans.
Mycobacterium chelonei, Mycobacterium fortuitum, Mycobacterium phlei, Mycobacterium smegmatis, Mycobacterium thermoresistible
Mycobacterium farcinogenes, Mycobacterium senegalense
associated with bovine farcy.
causes mycobacteriosis in birds.
found in tuberculin-positive cattle and causes limited lymph node lesions in pigs. Closely related to M. avium and also described as M. avium-intracellulare complex.
see M. avium subsp. paratuberculosis (above).
causes tuberculosis-like disease in pigs, deer and cattle.
the cause of leprosy in humans.
causes murine and feline leprosy.
found in water, it causes tuberculosis in fish and skin ulcers in humans.
the vole bacillus; lesions sometimes occur in other species.
previously called M. johnei. See M. avium subsp. paratuberculosis (above).
the tubercle bacillus of humans, but found also in monkeys and pigs, and rarely in cattle, dogs and parrots.
causes skin ulcers in humans and cats.
causes mycobacterial granuloma in cats and lymph node lesions in pigs.
