Overview


  • Yersinia kristensenii subsp. rochesterensis is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, coccobacillus bacterium. The DNA G+C content is 48.5%. Yersinia kristensenii subsp. rochesterensis is probably a rare gut coloniser. (Farmer1985; Cunningham2019; Bottone2005Bergey)



  • This organism has been recovered from human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal. Robust growth can have negative consequences for gut health.
