Colony characteristics


Differential characteristics

  • Phylogenetic position between rapidly and slowly growing mycobacteria.
  • M. asiaticum is phenotypically very similar, but can be distinguished by its growth at 22 °C, and by its dysgonic growth.

Type strain

  • Repeatedly isolated from sputum from a patient with pulmonary disease.

Strain 1669/91 = ATCC 51848 = CCUG 37583 = CIP 104542 = DSM 44049 = JCM 13572


The word origin is latin; intermedium, meaning between, rapidly and slowly growing mycobacteria.
