Overview

  • Yersinia alsatica is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped - curved bacterium. The DNA G+C content is 47.6%. Yersinia alsatica is probably a rare gut coloniser. (LeGuern2020)



  • This organism has been recovered from human faeces, France. Pathogenicity status unknown, or very unlikely to be pathogenic. Is a known gut commensal.
