Overview

  • Slackia piriformis is a Gram-positive, non-spore-forming, strictly anaerobic, non-motile, club-shaped-shaped bacterium. It has been detected in at least 8 gut microbiome compilation studies or metastudies. The DNA G+C content is 58.3%. Slackia piriformis is probably a common, although minor, coloniser of the gut. (Nagai2010a)



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