Overview

  • Brachyspira aalborgi is a Gram-negative, non-spore-forming, anaerobic, motile, spirochete bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 27.1%. Brachyspira aalborgi is probably a rare gut coloniser. (HovindHougen1982; Stanton2010Bergey)



  • This organism has been recovered from human faeces, and human colon. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). It is an opportunistic pathogen. A possible gut commensal. Robust growth can have negative consequences for gut health.
