Overview

  • Alistipes megaguti is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 58.6%. Alistipes megaguti is probably a rare gut coloniser. (Bellali2019)



  • This organism has been recovered from human faeces (Bellali2019). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
