Mycobacterium confluentis is a non-pathogenic bacterium of the oral cavity.
Gram-positive, nonmotile, acid-fast coccobacillus (0.5-0.8 μm x 0.7-1.7 μm), does not form spores, capsules or aerial hyphae.
Not associated with disease. Biosafety level 1.
First isolated from sputum, Koblenz, Germany. strain 1389/90 = ATCC 49920 = CIP 105510 = DSM 44017 = JCM 13671.
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.
Mycobacterium smegmatis is an acid-fast bacterial species in the phylum Actinomycetota and the genus Mycobacterium. It is 3.0 to 5.0 μm long with a bacillus shape and can be stained by Ziehl–Neelsen method and the auramine-rhodamine fluorescent method. It was first reported in November 1884 by Lustgarten, who found a bacillus with the staining appearance of tubercle bacilli in syphilitic chancres. Subsequent to this, Alvarez and Tavel found organisms similar to that described by Lustgarten also in normal genital secretions (smegma). This organism was later named M. smegmatis.
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 diernhoferi 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 flavescens 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 gadium is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gastri is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium genavense is a slow-growing species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium gilvum is a species of the phylum Actinomycetota, belonging to 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 heidelbergense is a Gram-positive, nonmotile, acid-fast coccobacillus. It is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium hodleri is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium interjectum is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium intermedium is a species of the phylum Actinomycetota, belonging to the genus Mycobacterium.
Mycobacterium madagascariense
Etymology: madagascariense, relating to Madagascar where it was first isolated.
Mycobacterium moriokaense
Etymology: moriokaense, from Morioka, Japan where the organism was first isolated.
Mycobacterium murale
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.
