Mycobacterium confluentis is a non-pathogenic bacterium of the oral cavity.
Description
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.
Physiology
- Rapid growth within 2 to 4 days on Löwenstein-Jensen media at 22°C, 31°C, 37°C and 41°C (optimum growth between 31°C and 37°C).
- In vitro susceptibility to isoniazid, ethambutol and streptomycin.
Differential characteristics
- 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.
Pathogenesis
Not associated with disease. Biosafety level 1.
Type strain
First isolated from sputum, Koblenz, Germany. strain 1389/90 = ATCC 49920 = CIP 105510 = DSM 44017 = JCM 13671.
