Overview


  • Limnochorda pilosa is a Gram-negative, spore-forming, facultatively anaerobic, pleiomorph rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 71%. Limnochorda pilosa is likely to be transient and not a long-term gut coloniser. (Watanabe2015)



  • This organism has been recovered from meromictic lake sediment, Japan. Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.

  • QUIRKS
  • High optimum growth temperature so unlikely to be a gut coloniser.
