Nontuberculous mycobacteria (NTM), also known as environmental mycobacteria, atypical mycobacteria and mycobacteria other than tuberculosis (MOTT), are mycobacteria which do not cause tuberculosis or leprosy. NTM do cause pulmonary diseases that resemble tuberculosis. Mycobacteriosis is any of these illnesses, usually meant to exclude tuberculosis. They occur in many animals, including humans and are commonly found in soil and water.
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.
Mycolicibacterium austroafricanum is a species of the phylum Actinomycetota, belonging to the genus Mycolicibacterium.
Mycobacterium boenickei is a member of the Mycobacterium fortuitum third biovariant complex. They are rapidly growing ubiquitous environmental organisms that normally inhabit soil, dust and water. These organisms frequently are human pathogens that cause a wide spectrum of clinically significant disease. It is important for practitioners to be aware of these organisms as possible etiological agents, as they are resistant to most first-line anti-tuberculous agents.
Mycobacterium brisbanense is a member of the Mycobacterium fortuitum third biovariant complex. They are rapidly growing ubiquitous environmental organisms that normally inhabit soil, dust and water. These organisms frequently are human pathogens that cause a wide spectrum of clinically significant disease. It is important for practitioners to be aware of these organisms as possible etiological agents, as they are resistant to most first-line anti-tuberculous agents.
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.
Mycobacterium conceptionense is a non pigmented rapidly growing mycobacterium was first isolated from wound liquid outflow, bone tissue biopsy, and excised skin tissue from a 31-year-old woman who suffered an accidental open right tibia fracture and prolonged stay in a river. Etymology: conceptionense, pertaining to Hôpital de la Conception, the hospital where the first strain was isolated.
Mycobacterium cosmeticum is a rapidly growing mycobacterium that was first isolated from cosmetic patients and sites performing cosmetic procedures.
Mycobacterium diernhoferi 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 goodii is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium.
Mycobacterium avium complex is a group of mycobacteria comprising Mycobacterium intracellulare and Mycobacterium avium that are commonly grouped because they infect humans together; this group, in turn, is part of the group of nontuberculous mycobacteria. These bacteria cause Mycobacterium avium-intracellulare infections or Mycobacterium avium complex infections in humans. These bacteria are common and are found in fresh and salt water, in household dust and in soil. MAC bacteria usually cause infection in those who are immunocompromised or those with severe lung disease.
Mycolicibacter kumamotonensis is a species of bacteria.
Etymology: kumamotonensis, pertaining to Kumamoto Prefecture in Japan, where the type strain was isolated.
Mycobacterium mageritense
Etymology: Magerit, is Arabic for Madrid, where it was first isolated from human sputum.
Mycobacterium neworleansense is a member of the Mycobacterium fortuitum third biovariant complex.
Mycobacterium wolinskyi is a rapidly growing mycobacterium most commonly seen in post-traumatic wound infections, especially those following open fractures and with associated osteomyelitis. Mycobacterium wolinskyi is clearly clinically significant, and occurs in the same settings as Mycobacterium smegmatis and members of the Mycobacterium fortuitum complex; they differ from members of the Mycobacterium fortuitum complex in the type of chronic lung disease they produce, with essentially all cases occurring in the setting of chronic lipoid pneumonia, either secondary to chronic oil ingestion or chronic aspiration. Etymology: Wolinsky, named after Emanuel Wolinsky in honour of, and in recognition for, significant contributions to the study of the non-tuberculous mycobacteria.
Rapid growing mycobacterium consists of organism of the Mycobacterium fortuitum group and Mycobacterium chelonae/Mycobacterium abscessus group and these usually cause subcutaneous abscesses or cellulitis following trauma in immunocompetent patients.
Mycobacterium saskatchewanense is a species of Mycobacterium.
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 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.
