Abstract

Alterations in gut microbiota are postulated to be an etiologic factor in the pathogenesis of irritable bowel syndrome (IBS). To determine whether IBS patients in China exhibited differences in their gut microbial composition, fecal samples were collected from diarrhea-predominant IBS (IBS-D) and healthy controls and evaluated by 16S ribosomal RNA gene sequence and quantitative real-time PCR. A mouse model of postinfectious IBS (PI-IBS) was established to determine whether the altered gut microbiota was associated with increased visceral hypersensitivity. The results indicated that there were significant differences in the bacterial community profiles between IBS-D patients and healthy controls. Prevotella was more abundant in fecal samples from IBS-D patients compared with healthy controls ( p < 0.05 ). Meanwhile, there were significant reductions in the quantity of Bacteroides , Bifidobacteria , and Lactobacillus in IBS-D patients compared with healthy controls ( p < 0.05 ). Animal models similarly showed an increased abundance of Prevotella in fecal samples compared with control mice ( p < 0.05 ). Finally, after the PI-IBS mice were cohoused with control mice, both the relative abundance of Prevotella and visceral hypersensitivity of PI-IBS mice were decreased. In conclusion, the altered intestinal microbiota is associated with increased visceral hypersensitivity and enterotype enriched with Prevotella may be positively associated with high risk of IBS-D.

  • Prevotella species associated with detrimental impacts on intestinal barrier integrity are enriched in IBS patients and in models of intestinal inflammation and may promote inflammatory arthritis.

    “Prevotella species associated with detrimental impacts on intestinal barrier integrity are enriched in IBS patients and in models of intestinal inflammation [52, 113] and may promote inflammatory arthritis [3, 104, 126].”

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.
