Description

Large, dispersed acid-fast bacilli with prominent beading

Colony characteristics

  • Colonies on Löwenstein-Jensen medium were nonchromogenic, small, with a dry appearance.
  • On Middlebrook 7H10 agar, colonies are small, non-pigmented and smooth to rough, with a slightly irregular edge. Younger colonies appeared slightly transparent.

    • Physiology

  • Growth was observed on Löwenstein-Jensen medium at two weeks at both 37 and 42 °C and at 3 weeks at 30 °C. At four weeks, very little growth was observed at 25 °C, and no growth was observed at 52 °C.

    • Pathogenesis

  • The causative agent of bursitis in an immunocompetent individual.

    • Type strain

  • Isolated from synovial tissue from a 68-year-old female with bursitis of her right elbow. The likely exposure was in a lake.

    • Strain NRCM 00-255 = ATCC BAA-323 = DSM 44577
