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.
