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.
Mycobacteriaceae is a family of bacteria in the phylum Actinomycetota. Its name is derived from the Mycobacterium genus, which 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.
Mycobacteroides abscessus is a species of rapidly growing, multidrug-resistant, nontuberculous mycobacteria (NTM) 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.
Mycobacteroides chelonae is a species of bacteria from the phylum Actinomycetota belonging to the genus Mycobacteroides. Mycobacteroides chelonae is a rapidly growing mycobacterium that is found all throughout the environment, including sewage and tap water. It can occasionally cause opportunistic infections of humans. It is grouped in Runyon group IV.
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.
Mycolicibacillus is a genus of Gram-Positive rod-shaped bacteria in the family Mycobacteriaceae from the order Mycobacteriales.
Mycobacteroides 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.
Mycolicibacillus parakoreensis is a slow-growing, non-chromogenic species of Mycolicibacillus originally isolated from the sputum of a human patient. It is susceptible to amikacin, clarithromycin, and rifampin.
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.
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 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 icosiumassiliensis" is a species of bacteria from the phylum Actinomycetota.
"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
