Contents

Etymology: Latin, flavescens = becoming golden yellow.

Description

Gram-positive, nonmotile and acid-fast rods.

Colony characteristics

  • Rough, yellow-orange scotochromogenic, butyrous colonies.

    • Physiology

  • Slow growth on Löwenstein-Jensen medium at 25-37°C, but not at 45 °C within 7–10 days.
  • Although growth rate is intermediate, metabolic and physiologic properties are more like rapidly growing species.

    • Differential characteristics

  • Serologic specificity demonstrated by immunodiffusion.
  • Related to Mycobacterium fortuitum: can be distinguished by its intense pigment production, and its slow rate of growth.

    • Pathogenesis

    Not associated with disease. Biosafety level 2.

    Type strain

  • Normal human flora, environmental habitat.
  • First isolated from a drug treated tuberculous guinea pig (Mexico).

    • Strain ATCC 14474 = CCUG 29041 = CIP 104533 = DSM 43991 = JCM 12274 = NCTC 10271 = NRRL B-4038.
