Mycobacterium is a genus of over 190 species in the phylum Actinomycetota, assigned its own family, Mycobacteriaceae. This genus includes pathogens known to cause serious diseases in mammals, including tuberculosis and leprosy in humans. The Greek prefix myco- means 'fungus', alluding to this genus' mold-like colony surfaces. Since this genus has cell walls with a waxy lipid-rich outer layer that contains high concentrations of mycolic acid, acid-fast staining is used to emphasize their resistance to acids, compared to other cell types.
Mycobacterium brumae is a rapidly growing environmental mycobacterial species identified in 1993. Aside from one 2004 report of a catheter related bloodstream infection no other infections by this organism have been reported. It was first isolated from water, soil and one human sputum sample in Spain.
Mycobacterium confluentis is a non-pathogenic bacterium of the oral cavity.
Mycobacterium cookii is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium diernhoferi is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium duvalii is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium elephantis, a bacterium of the family Mycobacteriaceae, was discovered and isolated from a deceased elephant near India and may be linked to respiratory dysfunction. Organisms in the genus Mycobacterium are known to be aerobic and non-motile. Organisms within Mycobacterium belong to either the rapid growing group or the slow growing group. M. elephantis is classified as a rapid grower and relates most closely to Mycobacterium confluentis and Mycobacterium phlei.
Mycobacterium fallax is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium flavescens is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium fortuitum is a nontuberculous species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gadium is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gastri is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium genavense is a slow-growing species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gilvum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gordonae is a species of Mycobacterium named for Ruth E. Gordon. It is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium haemophilum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium hassiacum is a rapid-growing thermophilic mycobacterium that was isolated in human urine in 1997 by researchers at the German University of Regensburg. It's a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium heidelbergense is a Gram-positive, nonmotile, acid-fast coccobacillus. It is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium interjectum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium lentiflavum
Etymology: Lentus from Latin for slow, flavus, Latin for yellow.
