Overview

  • Roseomonas gilardii 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 67.6-71.2%. Roseomonas gilardii is probably a rare gut coloniser. (Han2003; Rihs1993; SanchezPorro2009)



  • This organism has been recovered from potable water and clinical sources. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Is a known human pathogen. A possible gut commensal.
