Abstract

Classification of the human gut microbiome into distinct types, or "enterotypes," provides an attractive framework for understanding microbial variation in health and disease. However, as discussed here, several different methods of collapsing enterotype variation into a few discrete clusters suggest that enterotype distribution is continuous and can vary widely within an individual.

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

  • As with known enterotypes, defining taxa included Prevotella, Akkermansia, and Bifidobacterium.

    “Concordant with reported enterotypes in the human microbiome47,51,55, we identified microbiotype-defining taxa including Prevotella spp., Akkermansia spp. and Bifidobacterium spp. (Extended Data Fig. 9).”
  • The human gut contains several discrete, ecologically balanced communities (microbiotypes) that are resilient but can be changed by diet, drugs, and lifestyle.

    “The human gut microbiome includes multiple discrete ecologically balanced communities—hereafter referred to as ‘enteric microbiotypes’—that are resilient although still modifiable by diet, drugs and lifestyle47–52.”
  • Human gut microbiota variation includes discrete clusters or enterotypes, though their distribution may be continuous and composition can vary within an individual.

    “Human intestinal microbiota variation encompasses discrete microbial clusters or enterotypes, although their distribution may be continuous and their composition can be variable within the same individual47,50,51.”
  • The enterotype categorization has been criticized as an oversimplification that obscures potentially important microbial variation and may not be appropriate for the athletic population.

    “This categorization has been criticized as an oversimplification, obscuring potentially important microbial variation, and may not be appropriate for the athletic population [180, 181].”

  • CntA/B and yeaW/X contribute to TMA generation by converting carnitine into TMA.

    “Additional microbial enzyme systems that contribute to TMA generation are now known to include CntA/B and yeaW/X for conversion of carnitine into TMA226–230.”

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.
