Mycobacterium heidelbergense

Contents

Description

Gram-positive, and nonmotile, acid-fast, coccobacilli (0.5-0.8 µm x 2.0-3.0 µm).

Colony characteristics

Physiology

Differential characteristics

  • Differentiation from M. malmoense, (bearing a strong phenotypic resemblance to M. heidelbergense), by its wider range of susceptibility to antituberculous drugs, (including isoniazid), and by its inability to grow on Löwenstein-Jensen medium at 25°C.
  • Differentiation of M. triplex from M. heidelbergense by its positive nitrate reduction test and by its characteristic HPLC profile (triple-mycolate pattern).

Pathogenesis

Type Strain

Strain 2554/91 = ATCC 51253 = CIP 105424 = DSM 44471.
