Overview

  • Exiguobacterium marinum is a Gram-variable, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 48%. Exiguobacterium marinum is probably a rare gut coloniser. (Kim2005a)



  • This organism has been recovered from tidal flats and human faeces. 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.
