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 bohemicum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium caprae is a species of bacteria in the genus Mycobacterium and a member of the Mycobacterium tuberculosis complex. The species is named after the caprines, the organisms from which M. caprae was first isolated. Prior to 2003, the species was referred to as Mycobacterium tuberculosis subsp. caprae. It is also synonymous with the name Mycobacterium bovis subsp. caprae.
Mycolicibacter kumamotonensis is a species of bacteria.
Etymology: kumamotonensis, pertaining to Kumamoto Prefecture in Japan, where the type strain was isolated.
Mycobacterium lacus is a species of bacteria in the genus Mycobacterium known to be a causative agent in immunocompetent individuals.
Mycolicibacillus is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales.
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 salmoniphilum is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. It was first identified as the causative agent of mycobacteriosis in chinook salmon and steelhead trout, but has since been found to cause disease in Atlantic cod, Atlantic salmon, burbot, coho salmon, freshwater ornamental fish, and Russian sturgeon. It has also been isolated from tap water. It is not known to infect humans. M. salmoniphilum is susceptible to amikacin.
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 heraklionensis is a species of bacteria from the phylum Actinomycetota. It is susceptible to clarithromycin. It is known to cause tenosynovitis in humans, but has also been isolated from sputum, urine, and a soft-tissue ankle mass.
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 sinensis" is a species of bacteria from the phylum Actinomycetota that was isolated from a human manifesting tuberculosis-like disease. It is susceptible to ethambutol but is resistant to most other anti-tuberculosis drugs. It has also been isolated from domestic and wild animals.
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
