Abstract

Intestinal inflammation arises from abnormal host-microbe interactions. The perturbations of homeostatic coexistence involve host genetic factors, barrier function, innate and adaptive immunity, as well as qualitative and quantitative changes in the composition of the microbiota. Dysbiosis toward selected micro-organisms and decreased complexity of commensal bacteria have been observed in patients with Crohn's disease and ulcerative colitis, but it is not clear whether the dysbiosis contributes to development of inflammatory bowel disease or is instead a consequence of the disease. Pathogens with virulence factors that allow them to breach the intestinal barrier and induce chronic inflammation might mediate the pathogenesis of these diseases. To identify new therapeutic approaches for inflammatory bowel disease, it is important to identify host susceptibility factors involved in the control of microbial infection, characterize potential pathogens, and eliminate them or block the expression of their virulence factors.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • IBD is associated with decreased complexity in composition, with a loss of normal anaerobic bacteria, temporary composition instability during clinical remission, and dysbiosis towards selected microorganisms, with over- and under-representation of certain species.

    “There is a decreased complexity in composition, with a loss of normal anaerobic bacteria [33] , a temporary composition instability during clinical remission [34] , and a dysbiosis towards selected microorganisms, with over-and under-representation of certain species [35] .”

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.
