Overview

  • Butyrivibrio hungatei is a Gram-negative, non-spore-forming, strictly anaerobic, motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 41.6%. Butyrivibrio hungatei is likely to be transient and not a long-term gut coloniser. (Kopecny2003)



  • This organism has been recovered from 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. Likely to be transient and not a long-term gut commensal.
