Overview

  • Salmonella enterica subsp. enterica serovar Typhimurium, (aka Salmonella typhimurium), is a Gram-negative, non-spore-forming, facultatively anaerobic, motile, rod-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 50-53%. Salmonella enterica subsp. enterica serovar Typhimurium is probably a rare gut coloniser. (Popoff2005Bergey)



  • This organism has been recovered from human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: zoonotic pathogen). Is a known human pathogen. Unlikely to be a commensal. Robust growth can have negative consequences for gut health.
