Overview

  • Lactobacillus gigeriorum is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, short rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 41.9%. Lactobacillus gigeriorum is likely to be transient and not a long-term gut coloniser. (Rossi2016; Cousin2012)



  • This organism has been recovered from a chicken crop. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
