Abstract

A translational medicine pipeline is described where human gut microbial communities and diets are re-created in gnotobiotic mice and the impact on microbe and host is defined using metagenomics.

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

  • The majority of human and mouse research uses stool samples, which only partly reflect conditions along the digestive tract.

    “The majority of studies in humans and mice rely on faecal samples, which provide some representation of what is occurring throughout the digestive tract”
  • Stool sampling can hide features of the microbiota and host response that are unique to the small intestine.

    “aspects of microbial communities and host responses that are specific to the small intestine might be obscured by faecal sampling119,120.”
  • Our study corroborates previous studies showing an association between altered diets and an increase in Erysipelotrichi and Allobaculum.

    “Our study corroborates previous studies showing an association between altered diets and an increase in Erysipelotrichi and Allobaculum, but various effects are shown for fat-enriched diets 29, 30, 31, 32.”
  • High-fat diets in animal studies reproducibly change gut microbial community structure, decreasing overall microbiota diversity and beneficial bacteria and increasing the Firmicutes:Bacteroidetes ratio and abundance of Enterobacteriales, Clostridium cluster XVIa, Mollicutes, and B. wadsworthia.

    “Similar to the Western diet, high-fat diets in animal studies reproducibly change gut microbial community structure, decreasing the overall microbiota diversity and beneficial bacteria (e.g., A. muciniphila, Bifidobacterium, Lactobacillus, and Lactococcus) and increasing the Firmicutes:Bacteroidetes ratio and the abundance of Enterobacteriales, Clostridium cluster XVIa, Mollicutes, and B. wadswort”

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.
