Overview


  • Bacteroides caecimuris is a Gram-negative, non-spore-forming, anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 42.6%. Bacteroides caecimuris is probably a rare gut coloniser. (Lagkouvardos2016)



  • This organism has been recovered from mouse intestine and detected in human faeces (Alkhalil2017). Pathogenicity status unknown, or very unlikely to be pathogenic. A possible gut commensal.

  • GENERAL CHARACTERISTICS (Lagkouvardos2016);

  • indole;
  • Nitrate:
  • not reduced

  • N/A

  • Bacteroidetes maintain a complex and generally beneficial relationship with the host when retained in the gut, but when they escape this environment they can cause significant pathology, including bacteremia and abscess formation in multiple body sites. Genomic and proteomic analyses have vastly added to our understanding of the manner in which Bacteroides species adapt to, and thrive in, the human gut. A few examples are (i) complex systems to sense and adapt to nutrient availability, (ii) multiple pump systems to expel toxic substances, and (iii) the ability to influence the host immune system so that it controls other (competing) pathogens.

    Bacteroidetes is one of the major lineages of bacteria and arose early during the evolutionary process. Bacteroides species are anaerobic, bile-resistant, non-spore-forming, gram-negative rods. [PMID: 17934076]
