Overview

  • Lactobacillus hamsteri is a Gram-positive, non-spore-forming, strictly 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 34.1%. Lactobacillus hamsteri is probably a rare gut coloniser. (Mitsuoka1987; Hammes2011Bergey)



  • This organism has been recovered from hamster 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.
