[edit] 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.

[edit] Pathogenesis

• Not pathogenic
• Provokes a nonspecific skin hypersensitivity reaction to bovine tuberculin.
• Biosafety level 1

[edit] Type Strain

• First isolated from true moss, sphagnum and soil in Ireland

Strain Hi 11 = ATCC 49874 = CIP 104537 = DSM 44241 = JCM 13571.
