Overview


  • Haemophilus sputorum is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 6 gut microbiome compilation studies or metastudies. Haemophilus sputorum is probably a common, although minor, coloniser of the gut. (NorskovLauritsen2012)



  • This organism has been recovered from clinical sources (blood, oral cavity - CCUG) and human faeces. Can cause opportunistic infections, particularly in immunocompromised people. A possible gut commensal.

  • QUIRKS
  • In 11% of Europeans (unseenbio.com). Minor coloniser.

  • GENERAL CHARACTERISTICS (NorskovLauritsen2012);
    Character Response
  • H+
  • Acid from carbohydrates usually produced:
  • fructose; glucose; maltose; sucrose;
  • Active enzymes:
  • alkaline phosphatase; acid phosphatase; γ-Glu transferase; β-galactosidase; Leu arylamidase; oxidase; urease;

  • SPECIAL FEATURES (NorskovLauritsen2012);
    Character Response
  • Metabolites not produced:
  • H₂S; indole;
  • Haemolysis:
  • beta
