Description
[edit]Short gram-positive, nonmotile and acid-fast rods.
Colony characteristics
- Yellow-orange, scotochromogenic colonies, but the pigmentation deepens with exposure to light. Older cultures are more dry and rough.
Physiology
- Rapid growth on Löwenstein-Jensen medium at 28 °C and 37 °C, but not at 45 °C.
Pathogenesis
[edit]- Pathogenicity in humans is not known. Production of a local regressing infection but no death in mice.
- Biosafety level 1
Type strain
[edit]First isolated from known tuberculous patient from Cadiz, Spain. Strain ATCC 27726 = CCUG 37515 = CIP 105388 = DSM 44077 = HAMBI 2274 = JCM 12688 = NCTC 10942.
