Overview

  • Pseudobutyrivibrio ruminis is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped - curved bacterium. The DNA G+C content is 40.5%. Pseudobutyrivibrio ruminis is probably a rare gut coloniser.



  • This organism has been recovered from bovine rumen. The risk classification (www.baua.de) for this organism is 1, i.e., low risk of infection and spread. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
