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 lepraemurium is a causative agent of feline leprosy. It causes granulomatous lesions, characteristic of the Mycobacterium genus.
Mycolicibacterium alvei is a species of the phylum Actinomycetota, belonging to the genus Mycolicibacterium.
Mycolicibacter arupensis is a slowly growing mycobacterium first isolated from soil and human sputum samples in Spain. Etymology: arupense, pertaining to the ARUP Institute for Clinical and Experimental Pathology, where the type strain was characterized.
Mycobacterium asiaticum is a slowly growing photochromogenic mycobacterium first isolated from monkeys in 1965. M. asiaticum can, but rarely, causes human pulmonary disease.
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 diernhoferi is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium fallax is a 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 genavense is a slow-growing 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 intermedium is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium lentiflavum
Etymology: Lentus from Latin for slow, flavus, Latin for yellow.
Mariannaea elegans an anamorphic fungus. It is mainly found on rotting wood and soil. M. elegans is not pathogenic to humans, animals, or plants.
Mycolicibacter is a genus of gram-positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales.
Mycolicibacter engbaekii is a species of bacteria from the phylum Actinomycetota. It is susceptible to amikacin, clarithromycin, ethambutol, linezolid, and rifabutin. It has also been recovered from African tuberculosis patients, water treatment plant sludge, and dairy cattle.
Mycolicibacter minnesotensis is a species of bacteria from the phylum Actinomycetota that was first isolated from a sphagnum peat bog. It is pink-pigmented and grows at 27–34 °C. It has also been isolated from fresh produce and water treatment plant sludge.
Mycolicibacter paraterrae is a species of bacteria from the phylum Actinomycetota that was first isolated from the sputum of a patient with an unspecified pulmonary infection. It forms orange colonies when grown in the dark and grows slowly at 25–37 °C. It has also been isolated from
