Overview

  • Inhabit mucosal epithelium of upper respiratory and lower genital tract
  • Suppurative infections due to release of pro-inflammatory cytokines released from macrophages
  • Serofibrinous to fibrinopurative infections of lungs, body cavities and joints
  • Colonisation of meningeal vessels causes a thrombotic vasculitis leading to encephalitis and meningitis


Haemophilus characteristics

  • Morphologically variable Gram-negative bacilli, ranging from short rods to long filaments
  • Facultative anaerobes
  • Typically oxidase positive
  • Depend on beta-nicotinamide adenine dinucleotide (NAD) (V factor) and/or Haemin (X fector) for growth
  • Heated blood agar (Chocolate Agar) required for growth of NAD-dependent strains
  • Haemin-dependent strains grow on Blood Agar
  • Do not grow on MacConkey agar
