Overview

  • Streptococcus pseudoporcinus is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, oval-shaped bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. Streptococcus pseudoporcinus is probably a rare gut coloniser. (Bekal2006)



  • This organism has been recovered from the genitourinary tract of women. 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.
