Mycobacterium confluentis is a non-pathogenic bacterium of the oral cavity.

Description

[edit]

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

[edit]

Differential characteristics

[edit]
  • 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

[edit]

Not associated with disease. Biosafety level 1.

Type strain

[edit]

First isolated from sputum, Koblenz, Germany. strain 1389/90 = ATCC 49920 = CIP 105510 = DSM 44017 = JCM 13671.
