Overview


  • Prevotella nanceiensis is a Gram-negative, non-spore-forming, strictly anaerobic, non-motile, coccobacillus bacterium. It has been detected in at least 4 gut microbiome compilation studies or metastudies. The DNA G+C content is 42.6%. Prevotella nanceiensis is probably a rare gut coloniser. (Alauzet2007)



  • This organism has been recovered from clinical sources (blood, bacteremia - CCUG) and human faeces. The risk classification (www.baua.de) for this organism is 2, i.e., risk of individual infection, but low risk of spread. Could be a possible pathogen in humans, but unknown at this stage. A possible gut commensal.

  • Prevotella species at mucosal sites to localized and systemic disease, including periodontitis, bacterial vaginosis, rheumatoid arthritis, metabolic disorders and low_grade systemic inflammation. Intriguingly, Prevotella abundance is reduced within the lung microbiota of patients with asthma and chronic obstructive pulmonary disease. Increased Prevotella abundance is associated with augmented T helper type 17 (Th17) _mediated mucosal inflammation, which is in line with the marked capacity of Prevotella in driving Th17 immune responses in vitro. Studies indicate that Prevotella predominantly activate Toll_like receptor 2, leading to production of Th17_polarizing cytokines by antigen_presenting cells, including interleukin_23 (IL_23) and IL_1. Furthermore, Prevotella stimulate epithelial cells to produce IL_8, IL_6 and CCL20, which can promote mucosal Th17 immune responses and neutrophil recruitment. Prevotella_mediated mucosal inflammation leads to systemic dissemination of inflammatory mediators, bacteria and bacterial products, which in turn may affect systemic disease outcomes.

  • GutFeeling KnowledgeBase COMMENTS [Website]

    Prevotella species are anaerobic Gram_negative bacteria of the Bacteroidetes phylum, which also includes the clinically important genera Bacteroides and Porphyromonas. Prevotella strains are classically considered commensal bacteria due to their extensive presence in the healthy human body and their rare involvement in infections. Only a few strains have been reported to give rise to opportunistic endogenous infections, including chronic infections, abscesses and anaerobic pneumonia. [PMID: 28542929]
