Mycobacterium haemophilum

Description

Short, occasionally curved, gram-positive, nonmotile and strongly acid-fast rods.

Colony characteristics

  • Nonpigmented and rough to smooth colonies.

Physiology

  • Media have to be supplemented with 0.4% haemoglobin or 60µM hemin (factor X) or 15mg/ml ferric ammonium citrate respectively, but not with FeCl3 or catalase.
  • Slow growth on Löwenstein-Jensen media or Middlebrook 7H10 agar at 32°C within 2-4 weeks.
  • Growth slower at 25°C and 35°C and absent at 37°C.
  • Strictly intracellular growth in tissue cultures of fibroblasts.

Differential characteristics

  • Unique among mycobacteria in its requirement for hemin or ferric ammonium citrate for growth.

Distribution.

Pathogenesis

Type Strain

First isolated in Israel from a subcutaneous granuloma from a patient with Hodgkin's disease. An environmental reservoir is presumed. Strain ATCC 29548 = CCUG 47452 = CIP 105049 = DSM 44634 = NCTC 11185.

Treatment

Antimicrobial regimen

  • 1. In vitro [1]
  • 2. Disseminated disease
