Overview

  • Prevotella fusca is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 2 gut microbiome compilation studies or metastudies. The DNA G+C content is 43%. Prevotella fusca is likely to be transient and not a long-term gut coloniser. (Downes2011a)



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