Overview


  • Brachyspira hyodysenteriae, (aka Treponema hyodysenteriae), is a Gram-negative, non-spore-forming, microaerophilic, motile, helical-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 25-26%. Brachyspira hyodysenteriae is probably a rare gut coloniser. (Stanton2010Bergey; Ochiai1997; Kinyon1979; Stanton1991)



  • This organism has been recovered from the faeces of pigs and other mammals. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: opportunistic in immunocompromised patients). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.

  • QUIRKS
  • Cholesterol is required and is reduced to cholestanol.
