Overview

  • Agrococcus terreus is a Gram-positive, non-spore-forming, strictly aerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 75.9%. Agrococcus terreus is likely to be transient and not a long-term gut coloniser. (Zhang2010)



  • This organism has been recovered from forest soil and human faeces. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Obligate aerobe; unlikely to be a gut coloniser.
