Overview


  • Parabacteroides gordonii is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, rod-shaped bacterium. It has been detected in at least 9 gut microbiome compilation studies or metastudies. The DNA G+C content is 44.6%. Parabacteroides gordonii is probably a common, although minor, coloniser of the gut. (Sakamoto2009a)



  • This organism has been recovered from human faeces, and clinical sources (wound, blood - CCUG). Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.

  • Bacteroides and Parabacteroides species are components of the colon resident microbiota, and both genera belong to the order Bacteroidales. Species of these genera are often associated with opportunistic mixed infections, such as intra-abdominal, obstetric-gynecologic and diabetic foot infections. In addition, these microorganisms are able to develop resistance to several antimicrobial drugs. Although antibiotics with good activity against these bacteria are currently available, high frequencies of resistance to some antimicrobials have been reported in several countries. Bacteroides and Parabacteroides species produce endogenous �_-lactamases, the most important mechanism of resistance to �_-lactam antibiotics. [PMID: 21655744]
  • GutFeeling KnowledgeBase COMMENTS [Website] Bacteroides and Parabacteroides species are components of the colon resident microbiota, and both genera belong to the order Bacteroidales. [PMID: 21655744] Cells are Gram-negative, obligately anaerobic, non-spore-forming, non-motile and rod-shaped, and 0.8-1.6μm in size. Major end-products are acetic and succinic acids. [PMID: 16825636]
