Mycolicibacter hiberniae (formerly Mycobacterium hiberniae) is a species of bacteria in the phylum Actinomycetota.[1]

Etymology Hibernia, Latin for Ireland where it was first isolated.

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

Type strain

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