Decreased abundance of F aecalibacterium prausnitzii in the gut microbiota of C rohn's disease
Abstract
Background and Aims: Dysbiosis is thought to be relevant to the etiology and pathogenesis of C rohn's disease ( CD ). In this study, we investigated the abundance of F aecalibacterium prausnitzii , as well as B ilophila wadsworthia , in the gut microbiota of J apanese CD patients. Methods: Forty‐seven CD patients and 20 healthy controls were enrolled. Abundance of F . prausnitzii in fecal samples was quantified by real‐time polymerase chain reaction. The gut microbiota profile was evaluated by terminal restriction fragment length polymorphisms. Results: The abundance of F . prausnitzii significantly decreased in CD patients compared with healthy subjects. B . wadsworthia was scarcely detected in the same samples. Among CD patients, the C rohn's D isease A ctivity I ndex, C ‐reactive protein levels, and erythrocyte sedimentation rate were significantly lower, and serum albumin levels were significantly higher in the high F . prausnitzii group compared with the low group. Terminal restriction fragment length polymorphisms analysis showed that fecal bacterial communities of CD patients differed from those of healthy individuals. The changes in simulated bacterial composition indicated that class C lostridia, including genus F aecalibacterium, was significantly less abundant in CD patients as compared with healthy individuals. The bacterial diversity measured by the S hannon D iversity I ndex was significantly reduced in CD patients compared with healthy individuals. Conclusion: The decreased abundance of class C lostridia, including F . prausnitzii , may translate into a reduction of commensal bacteria‐mediated, anti‐inflammatory activities in the mucosa, which are relevant to the pathophysiology of CD . In contrast, the role of B . wadsworthia was suspected to be minimal.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
