Springer et al. 1995, ATCC 49650Mycobacterium mucogenicum
Etymology: mucogenicum, from the organism's highly mucoid appearance.Contents
Description
Gram-positive, nonmotile, curved and acid-fast rods.
Colony characteristics
- Highly mucoid behavior of most strains on solid agar. Smooth and off-white on Middlebrook 7H10 agar
Physiology
- Rapid growth on Middlebrook 7H10 at 28°C to 37°C, but not at 42°C, within 2 – 4 days.
- Susceptible to amikacin, imipenem, cefoxitin, clarithromycin and ciprofloxacin.
- Resistant to isoniazid and rifampin.
Pathogenesis
- Posttraumatic skin infections,
- catheter sepsis and respiratory isolates without clinical significance except in immunocompromised hosts.
- Biosafety level 2
Type strain
- First isolated in 1976 during an outbreak of peritonitis associated with automated peritoneal dialysis machines in the north-western United States.
- Strain ATCC 49650 = CCUG 47451 = CIP 105223 = DSM 44625 = JCM 13575.
