Mycobacterium, Mycobacterium aubagnense Adekambi et al. 2006.
Acid-fast bacilli. Gram-positive.
Colonies are non-pigmented and appear on 5% sheep blood agar, Middlebrook
7H10 agar and egg-based Lowenstein-Jensen slants in 2-5 days at temperatures
between 24 and 37 ºC, optimally at 30 ºC. No growth occurs at 42 ºC. No growth in 5%
(w/v) NaCl media or in MacConkey agar without crystal violet.
Associated with chronic pneumonia and sepsis.
Isolated from human bronchial aspirate.
Susceptible in vitro to amoxycillin, amoxycillin/clavulanate, cefoxitin, imipenem, minocycline, doxycycline, clarithromycin, erythromycin,
azithromycin, amikacin, tobramycin, ciprofloxacin, ofloxacin, sparfloxacin and trimethoprim/sulfamethoxazole.
