Overview


  • Hathewaya limosa, (aka Clostridium limosum), is a Gram-positive, spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. Hathewaya limosa is probably a rare gut coloniser. (Cato1970; Rainey2011bBergey)



  • This organism has been recovered from human faeces, clinical sources, and animal disease. 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. Is a known gut commensal.
