Overview

  • Kurthia gibsonii is a Gram-positive, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 36-38%. Kurthia gibsonii is probably a rare gut coloniser. (Shaw1983; Pukall2011Bergey)



  • This organism has been recovered from animal faeces and human faeces. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). Can cause opportunistic infections, particularly in immunocompromised people. Is a known gut commensal. Robust growth can have positive consequences for gut health.
