Overview


  • Bacteroides congonensis is a Gram-negative, non-spore-forming, anaerobic, motile, coccobacillus bacterium. It has been detected in at least 3 gut microbiome compilation studies or metastudies. The DNA G+C content is 43.0%. Bacteroides congonensis is a common gut coloniser. (Andrieu2018; Bilen2016)



  • This organism has been recovered from human faeces (CCUG). Pathogenicity status unknown, or very unlikely to be pathogenic. Likely to be transient and not a long-term gut commensal.
