Description
Polymorphic, beaded, gram-positive, nonmotile and acid-fast rods (0.9 μm × 1.2–1.5 μm).
Colony characteristics
- Smooth and glistening colonies with rose-pink pigmentation but become rough and dry later. Colonies with unique pigment production are 1-1.5 mm in diameter.
Physiology
- Slow growth on Löwenstein-Jensen medium and Middlebrook 7H10 agar at 37 °C (range: 22-37 °C). No growth at 42 °C.
- Resistant to isoniazid, rifampin, and streptomycin
- Sensitive to ethambutol.
Differential characteristics
- M. hiberniae has unusual rose-pink pigmentation, which is unique in the genus Mycobacterium.
Pathogenesis
- Not pathogenic
- Provokes a nonspecific skin hypersensitivity reaction to bovine tuberculin.
- Biosafety level 1
