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.
- Differentiation from other thermotolerant mycobacteria by its inability to grow at temperatures of more than 41°C.
- Separation from other rapidly growing mycobacteria by its susceptibility to antituberculotic drugs.
- Differentiated from the phenotypic closely related M. thermoresistibile by its inability to grow at 52°C.
Not associated with disease. Biosafety level 1.
First isolated from sputum, Koblenz, Germany. strain 1389/90 = ATCC 49920 = CIP 105510 = DSM 44017 = JCM 13671.
