Mycobacterium hiberniae 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.
Etymology Hibernia, Latin for Ireland where it was first isolated.
Description
Polymorphic, beaded, gram-positive, nonmotile and acid-fast rods (0.9 µm x 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
Type strain
Strain Hi 11 = ATCC 49874 = CIP 104537 = DSM 44241 = JCM 13571.
