mycobacteria

[mī′kōbaktir′ē·ə]
Etymology: Gk, mykes + bakterion, small rod
acid-fast microorganisms belonging to the genus Mycobacterium. mycobacterial, adj.

my·co·bac·te·ri·a

(mī'kō-bak-tēr'ē-ă)
Organisms belonging to the genus Mycobacterium.

Mycobacteria

AEROBIC, non-motile, rod-shaped Gram-positive BACTERIA (see GRAM'S STAIN), some of which are found in soil. Others are important PATHOGENS of man and ANIMALS, for example Mycobacterium leprae, which is the causative agent of LEPROSY, and Mycobacterium tuberculosis which is the causative agent of TUBERCULOSIS. The name ‘Mycobacterium’ derives from the occasional ability of organisms to produce filamentous growth (see MYCO-).

mycobacteria

members of the genus Mycobacterium.

anonymous mycobacteria

opportunist (atypical) mycobacteria
saprophytic mycobacteria which may cause disease in animals. Included are M. chelonae, M. fortuitum, M. phlei, M. smegmatis. Called also anonymous and nontuberculous. See also runyon classification, opportunist mycobacterial granuloma.
rapid growing mycobacteria
a distinguishing characteristic used for classifying mycobacteria, based on growth rate in cultures. Rapid growth is defined as less than 7 days. This group includes the saprophytic or opportunist mycobacteria, only some of which are associated with disease.
slow growing mycobacteria
these mycobacteria take more than 7 days for the appearance of colonies. This group includes the tubercle bacilli, M. avium, M. bovis and M. tuberculosis, and many of the others pathogenic for animals and humans.
