Mycobacterium mucogenicum
Etymology: mucogenicum, from the organism's highly mucoid appearance.

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.

Posttraumatic skin infections,
catheter sepsis and respiratory isolates without clinical significance except in immunocompromised hosts.
Biosafety level 2

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.
