(mī'kō-bak-tēr'ē-ŭm ā'vē-ŭm)
A bacterial species causing tuberculosis in fowl and other birds. Linked to opportunistic infections in humans.
Synonym(s): tubercle bacillus (3) .


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.

Mycobacterium avium
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.
Mycobacterium avium-intracellulare
complex see M. intracellulare (below).
Mycobacterium bovis
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
cause disease in a number of animal species, including mastitis in cattle and cutaneous mycobacterial granuloma in cats and dogs. See also opportunist (atypical) mycobacteria.
Mycobacterium farcinogenes, Mycobacterium senegalense
associated with bovine farcy.
Mycobacterium genovense
causes mycobacteriosis in birds.
Mycobacterium intracellulare
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.
Mycobacterium johnei
see M. avium subsp. paratuberculosis (above).
Mycobacterium kansasii
causes tuberculosis-like disease in pigs, deer and cattle.
Mycobacterium leprae
the cause of leprosy in humans.
Mycobacterium lepraemurium
causes murine and feline leprosy.
Mycobacterium marinum
found in water, it causes tuberculosis in fish and skin ulcers in humans.
Mycobacterium microti
the vole bacillus; lesions sometimes occur in other species.
Mycobacterium paratuberculosis
previously called M. johnei. See M. avium subsp. paratuberculosis (above).
Mycobacterium tuberculosis
the tubercle bacillus of humans, but found also in monkeys and pigs, and rarely in cattle, dogs and parrots.
Mycobacterium ulcerans
causes skin ulcers in humans and cats.
Mycobacterium xenopi
causes mycobacterial granuloma in cats and lymph node lesions in pigs.
