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 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 botniense is a slowly growing Mycobacterium, which produces a yellow pigment. It was first isolated from a stream of water. M. botniense is most closely related to Mycobacterium xenopi. Etymology: botniense; of Botnia, referring to the Latin name of the province of Finland from which the isolation was made.
Mycobacterium branderi is a slowly growing, nonchromogenic Mycobacterium first isolated from patients in Finland. Etymology: of Brander, referring to Eljas Brander, the former head of the Tuberculosis Laboratory of the National Public Health Institute, Finland, who collected the strains.
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 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 elephantis, a bacterium of the family Mycobacteriaceae, was discovered and isolated from a deceased elephant near India and may be linked to respiratory dysfunction. Organisms in the genus Mycobacterium are known to be aerobic and non-motile. Organisms within Mycobacterium belong to either the rapid growing group or the slow growing group. M. elephantis is classified as a rapid grower and relates most closely to Mycobacterium confluentis and Mycobacterium phlei.
Mycobacterium fallax 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 haemophilum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium houstonense is a member of the Mycobacterium fortuitum third biovariant complex. The specific epithet houstonense refers to Houston, Texas, where the first isolate of the M. fortuitum third biovariant (sorbitol-positive) was identified.
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.
Mycobacterium kansasii is a bacterium in the Mycobacterium genus. It is an environmental bacteria that causes opportunistic infections in humans, and is the one of the leading mycobacterial causes of human disease after tuberculosis and leprosy.
Mycobacterium lacus is a species of bacteria in the genus Mycobacterium known to be a causative agent in immunocompetent individuals.
Mycobacterium mucogenicum
Etymology: mucogenicum, from the organism's highly mucoid appearance.
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.
