Mycobacterium, Mycobacterium vulneris van Ingen et al. 2009.
Member of the Mycobacterium avium complex.
Acid-alcohol-fast short rods, with occasional coccoid forms. No cording, spores or
filaments are present.
Colonies are small, scotochromogenic and bright yellow. On Middlebrook 7H10,
Ogawa and Stonebrink media, mature growth develops after 28 days incubation at 36
°C. Growth is slower at 25 and 30 °C. No growth at 42 °C. No growth on MacConkey
Isolated from a leg wound of a 42-year-old woman, 7 weeks after a dogbite.
Resistant to isoniazid, thiophen-2-carboxylic acid hydrazide (TCH) (10 µg/ml), isoniazid (500 µg/ml), p-nitrobenzoic acid and
