Mycobacterium asiaticum is a slowly growing photochromogenic mycobacterium first isolated from monkeys in 1965. M. asiaticum can, but rarely, causes human pulmonary disease.

Description

[edit]

Microscopy

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

Colony characteristics

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

Physiology

Differential characteristics

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

Pathogenesis

[edit]
  • Rarely causes human pulmonary disease.

Type strain

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