Overview


  • Clostridium argentinense is a Gram-positive, spore-forming, anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 28-30%. Clostridium argentinense is probably a rare gut coloniser. (Suen1988)



  • This organism has been recovered from soil, amniotic fluid, autopsy specimens, blood and wounds, Argentina. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. A possible gut commensal.

  • QUIRKS
  • Produces phenylacetic acid as a fermentation byproduct; doesn't ferment sugars. May produce neuroparalytic toxins (botulinum toxin). Doesn't produce indole but can produce an indole derivative.

  • GENERAL CHARACTERISTICS (Suen1988);
    Character Response
  • Substrates hydrolysed or digested:
  • arginine; gelatin; milk;
  • Substrates assimilated or utilised:
  • arginine; serine;
  • ±
  • Strain-dependent active enzymes:
  • Leu arylamidase; Pro arylamidase; pyroGlu arylamidase;

  • SPECIAL FEATURES (Suen1988);
    Character Response
  • Metabolites produced:
  • acetate; butyrate; isobutyrate; isovalerate;
  • Metabolites not produced:
  • indole;
  • Haemolysis:
  • beta
