Overview

  • Yersinia mollaretii, (aka Yersinia enterocolitica biogroup 3A), is a Gram-negative, non-spore-forming, facultatively anaerobic, variably-motile, coccobacillus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 50-51%. Yersinia mollaretii is probably a rare gut coloniser. (Wauters1988; Bottone2005Bergey)



  • This organism has been recovered from human faeces (CCUG), drinking water, vegetables. 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. A possible gut commensal.
