Abstract

Distinct bacterial trophic networks exist in the gut microbiota of individuals in industrialized and non-industrialized countries. In particular, non-industrialized gut microbiomes tend to be enriched with Prevotella species. To study the development of these Prevotella-rich compositions, we investigated the gut microbiota of children aged between 7 and 37 months living in rural Gambia (616 children, 1,389 stool samples, stratified by 3-month age groups). These infants, who typically eat a high-fibre, low-protein diet, were part of a double-blind, randomized iron intervention trial (NCT02941081) and here we report the secondary outcome. We found that child age was the largest discriminating factor between samples and that anthropometric indices (collection time points, season, geographic collection site, and iron supplementation) did not significantly influence the gut microbiome. Prevotella copri, Faecalibacterium prausnitzii and Prevotella stercorea were, on average, the most abundant species in these 1,389 samples (35%, 11% and 7%, respectively). Distinct bacterial trophic network clusters were identified, centred around either P. stercorea or F. prausnitzii and were found to develop steadily with age, whereas P. copri, independently of other species, rapidly became dominant after weaning. This dataset, set within a critical gut microbial developmental time frame, provides insights into the development of Prevotella-rich gut microbiomes, which are typically understudied and are underrepresented in western populations.

  • The post-weaning diet, typically rich in high-fiber plant foods in sub-Saharan Africa, may play an important role in modulating the microbiota and selecting for specific strains.

    “The post-weaning diet, typically rich in high-fiber plant foods in sub-Saharan Africa, may also play an important role in modulating the microbiota and selecting for specific strains [100,101] .”

    From Genome-scale insights into the metabolic landscape and evolutionary development of Bifidobacterium bifidum (2026) · cites this paper as [101]

    The Methods (Participants; page unavailable) describe plant-based foods introduced during weaning in rural Gambia. The Results (Visualization of the maturation of the gut microbiome; page unavailable) report changes in bacterial species after weaning, and the Discussion links Prevotella to high-fibre diets and dietary shifts. The paper does not establish that the post-weaning diet selects specific strains, or that the described diet is typical across sub-Saharan Africa. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • A study based on 16S rRNA gene sequencing confirmed in children from a non-westernized Gambian community that P. copri, F. prausnitzii, and P. stercorea were the most abundant species in the infant gut microbiome and increased gradually with age.

    “Recently, a study based on 16S rRNA gene sequencing confirmed these results in children from a non-westernized Gambian community, where P. copri, F. prausnitzii, and P. stercorea were the most abundant species in the infant gut microbiome,58 and they increased gradually with age.”

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.
