Overview


  • Prevotella ihumii 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 42.1%. Prevotella ihumii is probably a rare gut coloniser. (Guilhot2017; Anani2019a)



  • This organism has been recovered from a stool specimen of a healthy adult. Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.
