Description

Microscopy

  • Gram-positive, nonmotile, acid-fast, coccoid rods.

Colony characteristics

  • Dysgonic and yellow photochromogenic (pigment not produced in the dark) colonies.

Physiology

  • Slow growth on Löwenstein-Jensen medium at 37°C after 15–21 days.

Differential characteristics

  • Unique 16S rRNA sequence.
  • Biochemically M. asiaticum (photochromogenic) and Mycobacterium gordonae (scotochromogenic) can only by the mode of pigmentation.

Pathogenesis

  • Rarely causes human pulmonary disease.

Type strain

  • First isolated from monkeys in 1965.
  • Strain ATCC 25276 = CCUG 29115 = CIP 106809 = DSM 44297 = JCM 6409.
