Overview

  • Pseudoruegeria marinistellae, (aka Tropicimonas marinistellae), is a Gram-negative, non-spore-forming, facultatively anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 1 gut microbiome compilation study or metastudy. The DNA G+C content is 63%. Pseudoruegeria marinistellae is probably a rare gut coloniser. (Zhang2017)



  • This organism has been recovered from a starfish, China. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
