Mycobacterium xenopi is a slow-growing scotochromogenic species of Mycobacterium. It was first reported by Schwabacher in 1959, having been isolated in lesions found on a Xenopus laevis, but the possibility of human infection was not confirmed until 1965. It has been cultured from hot and cold water taps, hospital hot water generators and storage tanks, and other environmental sources.
Mycobacterium phlei is a species of acid-fast bacteria in the genus Mycobacterium. It is characterized as one of the fast-growing mycobacteria. M. phlei has only occasionally been isolated in human infections, and patients infected with M. phlei generally respond well to anti-mycobacterial therapy. M. phlei has an unusually high GC-content of 73%.
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 asiaticum is a slowly growing photochromogenic mycobacterium first isolated from monkeys in 1965. M. asiaticum can, but rarely, causes human pulmonary disease.
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 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 duvalii is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
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 goodii is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium.
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.
Mycobacterium heckeshornense is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium kubicae is a Gram-positive, nonmotile and acid-fast bacterial species. Cells are typically rod-shaped, with some coccoid forms. Colonies of M. kubicae on solid media are generally smooth and domed, with a yellow scotochromogenic pigment. On Löwenstein-Jensen media they appear film-like. This species is not known to be pathogenic to humans. The species is named after American mycobacteriologist George Kubica.
Mycobacterium mageritense
Etymology: Magerit, is Arabic for Madrid, where it was first isolated from human sputum.
Mycobacterium nebraskense is a slow growing, yellow, pigmented mycobacterium that was first isolated from human sputum at the University of Nebraska Medical Center, in Omaha, Nebraska, USA. Mycobacterium species are common causes of pulmonary infections in both humans and animals.
Mycobacterium tusciae is a slow-growing, scotochromogenic mycobacterium first isolated from a lymph node of an immunocompromised child and subsequently from tap water and from a respiratory specimen of a patient with chronic fibrosis. Etymology: tusciae referring to the Italian region of Tuscany, where the organisms were first isolated.
Mycobacterium palustre is a slowly growing mycobacterium first isolated from an environmental source in Finland. It is potentially pathogenic, and has been isolated from human and veterinary clinical specimens.
Mycobacterium shimoidei is a slowly growing non-pigmented species of mycobacteria. It is rarely associated with lung disease in humans. It was first isolated in 1975.
Mycobacterium triplex is a species of Mycobacterium.
Mycobacterium parmense is a species of Mycobacterium.
