Roseburia faecis

RANK: Species

TAXONOMY: Terrabacteria group -> Firmicutes -> Clostridia -> Clostridiales -> Lachnospiraceae -> Roseburia -> Roseburia faecis


Roseburia faecis is a bacterium first isolated from human faeces. It is anaerobic, gram-negative or Gram-variable, slightly curved rod-shaped and motile. The cells range in size from 0.5-1.5 to 5.0 micrometres.

This species has been identified as a resident in the human gastrointestinal tract based on the phylogenetic framework of its small subunit ribosomal RNA gene sequences.[PMC 4262072]
