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.
Mycobacteroides abscessus is a species of rapidly growing, multidrug-resistant, nontuberculous mycobacteria that is a common soil and water contaminant. Although M. abscessus most commonly causes chronic lung infection and skin and soft tissue infection (SSTI), it can also cause infection in almost all human organs, mostly in patients with suppressed immune systems. Amongst NTM species responsible for disease, infection caused by M. abscessus complex are more difficult to treat due to antimicrobial drug resistance.
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 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.
Mycobacteroides immunogenum is a species of bacteria from the phylum Actinomycetota, belonging to the genus Mycobacteroides.
Mycolicibacter kumamotonensis is a species of bacteria.
Etymology: kumamotonensis, pertaining to Kumamoto Prefecture in Japan, where the type strain was isolated.
Mycobacterium triplex is a species of Mycobacterium.
Mycolicibacter terrae is a slow-growing species of mycobacteria. It is an ungrouped member of the third Runyon. It is known to cause serious skin infections, which are "relatively resistant to antibiotic therapy".
Mycobacterium arosiense is a newly described species of Mycobacterium. It is a scotochromogen that derives its name from Arosia, the Latin name for the city of Aarhus (Denmark), where the strain was first isolated.
Mycoobacterium iranicum is a bacterium from the genus Mycobacterium which has been isolated from a patient from Isfahan in Iran. Eight strains have been isolated from patients from various countries.
Mycolicibacillus koreensis is a slow-growing, non-chromogenic species of Mycolicibacillus originally isolated from the sputum of a human patient. It grows at temperatures from 25–37 °C and is susceptible to quinolones. The genome of M. koreensis contains a tRNA array that contains a long non-coding RNA called GOLDD.
Mycobacteroides franklinii is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. Most of the original strains were isolated from clinical specimens in Pennsylvania, but some have been found in conduit water in the Netherlands. In general, human M. franklinii infections present with symptoms similar to an infection with Mycobacteroides abscessus, but it can also be associated with tattoo infections. M. franklinii is also associated with outbreaks of mycobacteriosis in farmed fish. M. fanklinii is susceptible to cefoxitin and bedaquiline.
Mycobacteroides saopaulense is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides that was first isolated from a human patient undergoing LASIK surgery. It has also been isolated from turtles and cows. A strain isolated from mangroves has been demonstrated to produce clavulanic acid and streptomycin. The genome of M. saopaulense contains a tRNA array that contains a long non-coding RNA called GOLDD. M. saopaulense is susceptible to amikacin, kanamycin, and clarithromycin.
Mycolicibacter algericus is a species of bacteria from the phylum Actinomycetota that was first isolated from the lung lesion of a goat. It is non-pigmented and grows slowly at 25–42 °C on Löwenstein–Jensen medium. It has also been isolated from freshwater fish, fresh produce, water treatment plant sludge, and a natural cave.
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 longobardus is a species of bacteria from the phylum Actinomycetota. It is susceptible to sulfamethoxazole and clarithromycin. It has been associated with cases of osteomyelitis and an epidermal inclusion cyst of the hand,
"Mycolicibacter virginiensis" is a species of bacteria from the phylum Actinomycetota. It is susceptible to clarithromycin, ethambutol, rifabutin, and TMP-SMX. It has been isolated from cases of tenosynovitis, swine farm mud, bovine feces, sputum, and diseased dromedaries.
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 senuensis 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 is non-pigmented and grows slowly at 25–37 °C. It has also been isolated from swine.
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
