Overview

  • Lentilactobacillus hilgardii, (aka Lactobacillus hilgardii), is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 39-41%. Lentilactobacillus hilgardii is probably a rare gut coloniser. (Hammes2011Bergey)



  • This organism has been recovered from wines and human faeces. 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.
