Mycobacterium, Mycobacterium lehmannii Nouioui et al. 2017.
Acid-alcohol-fast rods. Gram-positive. Non-motile.
Colonies after 5 days incubation at 37 ºC on Middelbrook 7H10, Lowenstein-Jensen,
proteose peptone–meat extract-glycerol, glucose-yeast extract-malt extract and tryptic
soy agar plates are yellow-orange. Grows at 28-37 ºC, optimally at 37 ºC, and at pH7.
No growth at 10, 25 or 45 ºC. Grows in the presence of 4% w/v NaCl, but not in 8%
NaCl. Facultatively anaerobic.
Source of isolation is unknown.
Resistant to aztreonam, lithium chloride, nalidixic acid, rifamycin and potassium tellurite. Susceptible to sodium bromate, guanidine
hydrochloride, tetrazolium blue, tetrazolium violet, vancomycin, fusidic acid, lincomycin, minocycline, niaproof and troleandomycin.
