Overview

  • Leuconostoc carnosum is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, coccus bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 39%. Leuconostoc carnosum is likely to be transient and not a long-term gut coloniser. (Shaw1989; Holzapfel2011Bergey)



  • This organism has been recovered from human faeces (Sanz2007 -coeliac children) and vacuum-packaged meat. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Can't grow at 37C, so unlikely to be a gut coloniser.
