Mycobacterium intracellulare is a species of the phylum actinobacteria (Gram-positive bacteria with high guanine and cytosine content, one of the dominant phyla of all bacteria), belonging to the genus Mycobacterium.

Description[edit]

"Gram-positive", nonmotile and acid-fast short to long rods.

Physiology

Differential characteristics

Pathogenesis[edit]

  • Most frequently encountered in pulmonary secretions from patients suffering from tuberculosis-like disease and from surgical specimens from such patients.
  • When isolated from human secretions, it is often the etiologic agent of pulmonary disease, although frequently isolated as apparent casual resident
  • Biosafety level 2

Type strain[edit]

  • First isolated from fatal systemic disease in a child. Found in soil and water.

Strain ATCC 13950 = CCUG 28005 = CIP 104243 = DSM 43223 = JCM 6384 = NCTC 13025.
