Mycobacterium pseudoshottsii, a slowly growing chromogenic species was isolated from Chesapeake Bay striped bass during an epizootic of mycobacteriosis.
Mycobacterium arupense is a rapidly 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 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 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 canariasense is a rapidly growing, non-pigmented mycobacterium first isolated from blood samples obtained from 17 patients with febrile syndrome. Etymology: canariasense; referring to the Latin adjective of the Spanish islands where all strains were isolated.
Mycobacterium duvalii is a species of the phylum Actinobacteria, 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 fallax is a species of the phylum Actinobacteria, belonging to the genus Mycobacterium.
Mycobacterium gastri is a species of the phylum Actinobacteria, belonging to the genus Mycobacterium.
Mycobacterium hodleri is a species of the phylum Actinobacteria, belonging to the genus Mycobacterium.
Mycobacterium interjectum is a species of the phylum Actinobacteria, 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 lentiflavum
Etymology: Lentus from Latin for slow, flavus, Latin for yellow.
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.
Mycobacterium vanbaalenii is a rapidly growing mycobacterium that can use polycyclic aromatic hydrocarbons. It was first isolated from petroleum-contaminated estuarine sediments and has been shown by 16S rRNA gene sequencing to be closely related to Mycobacterium aurum and Mycobacterium vaccae. M. vanbaalenii has potential use in the bioremediation of polycyclic aromatic hydrocarbon contaminated environmental sites. Etymology: vanbaalenii of Van Baalen, in memory of Dr Chase Van Baalen, late Professor at The University of Texas Marine Science Institute, Port Aransas Marine Laboratory, Port Aransas, TX, USA.
Mycobacterium pyrenivorans is a scotochromogenic, rapidly growing mycobacterium, first isolated from an enrichment culture obtained from soil that was highly contaminated with polycyclic aromatic hydrocarbons (PAHs). The soil sample was collected on the site of a former coking plant at Ubach-Palenberg, Germany. Etymology: pyrenivorans; digesting pyrene.
In microbiology, the phenotypic testing of mycobacteria uses a number of methods. The most-commonly used phenotypic tests to identify and distinguish Mycobacterium strains and species from each other are described below.
