Overview

  • Paremcibacter congregatus, (aka Emcibacter congregatus), is a Gram-negative, non-spore-forming, aerobic, motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 51.5%. Paremcibacter congregatus is likely to be transient and not a long-term gut coloniser. (Park2020; Zhao2018)



  • This organism has been recovered from coastal sediment, China. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
    • QUIRKS
  • Low maximum growth temperature (30C) and aerobic requirements makes this a very unlikely gut coloniser.
