Overview

  • Dysgonomonas mossii is a Gram-negative, non-spore-forming, anaerobic, non-motile, coccobacillus bacterium. It has been detected in at least 5 gut microbiome compilation studies or metastudies. The DNA G+C content is 38.5%. Dysgonomonas mossii is probably a rare gut coloniser. (Hahnke2016; Lawson2002)



  • This organism has been recovered from human faeces and clinical samples (blood, abdominal drainage - CCUG). The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread (notes: opportunistic in immunocompromised patients). It is an opportunistic pathogen. A possible gut commensal.
