Acid-fast bacillus.
Colonies are yellow, scotochromogenic and grows aerobically within 7 days on
standard mycobacterial media.
Isolated from blood and posttraumatic wound or postsurgical infections.
Undetermined. Produce catheter-related infections.
It is susceptible (100%) to amikacin, cefoxitin, imipenem, trimethoprim-sulfamethoxazole, doxycycline, minocycline, tigecycline,
linezolid, ciprofloxacin, moxifloxacin, and gatifloxacin. It shows variable susceptibility to clarithromycin.
