Abstract

Recent studies suggest that gut microbiomes of urban-industrialized societies are different from those of traditional peoples. Here we examine the relationship between lifeways and gut microbiota through taxonomic and functional potential characterization of faecal samples from hunter-gatherer and traditional agriculturalist communities in Peru and an urban-industrialized community from the US. We find that in addition to taxonomic and metabolic differences between urban and traditional lifestyles, hunter-gatherers form a distinct sub-group among traditional peoples. As observed in previous studies, we find that Treponema are characteristic of traditional gut microbiomes. Moreover, through genome reconstruction (2.2–2.5 MB, coverage depth × 26–513) and functional potential characterization, we discover these Treponema are diverse, fall outside of pathogenic clades and are similar to Treponema succinifaciens, a known carbohydrate metabolizer in swine. Gut Treponema are found in non-human primates and all traditional peoples studied to date, suggesting they are symbionts lost in urban-industrialized societies.

  • Gut microbiota of eight hunter-gatherer or rural farming populations has greater bacterial diversity than Western populations.

    “The gut microbiota of eight hunter–gatherer or rural farming populations in various parts of the world showed increased bacterial diversity compared with those of Western populations19,40,52–55.”
  • The gut bacteria of urban-industrialized populations often have high abundances of Bacteroides, while the gut bacteria from traditional hunter-gatherer or agropastoral societies have higher abundances of Prevotella.

    “The gut bacteria of urban-industrialized populations often have high abundances of Bacteroides, while the gut bacteria from traditional hunter-gatherer or agropastoral societies have higher abundances of Prevotella [22–28].”
  • Bacteroides has been used to distinguish between developing (low Bacteroides abundance) and industrialized (high Bacteroides abundance) populations.

    “Bacteroides has been used to distinguish between developing (low Bacteroides abundance) and industrialized (high Bacteroides abundance) populations [22–28, 30]”
  • The Hadza have the highest abundance of Prevotellaceae and Spirochetaceae among populations in this cohort.

    “they have the highest abundance of Prevotellaceae and Spirochetaceae [24–27, 30]”
  • Treponema within family Spirochetaceae is a common constituent of hunter-gatherer gut microbiomes and a catabolizer of fibrous plant materials (cellulose and xylans) that form a large component of Hadza diets.

    “in particular, the genus Treponema within family Spirochetaceae, which is a common constituent of hunter-gatherer gut microbiomes [24–27, 30] and a catabolizer of fibrous plant materials (cellulose and xylans) that form a large component of Hadza diets [24]”

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.
