Overview


  • Moellerella wisconsensis is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Moellerella wisconsensis is probably a rare gut coloniser. (Farmer1985; HickmanBrenner1984; Farmer2005dBergey)



  • This organism has been recovered from human faeces and clinical sources (wound, sputum, peritoneum exsudate - CCUG). The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. It is an opportunistic pathogen. A possible gut commensal.
