Overview


  • Streptococcus acidominimus is a Gram-positive, non-spore-forming, facultatively anaerobic, non-motile, coccus bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 39.7%. Streptococcus acidominimus is likely to be transient and not a long-term gut coloniser. (Whiley2011Bergey; Shewmaker2017)



  • This organism has been recovered from cattle and milk. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread (notes: human and animal pathogen). Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
