Abstract

The composite members of the microbiota face a range of selective pressures and must adapt to persist in the host. We highlight recent work characterizing the evolution and transfer of genetic information across nested scales of host-associated microbiota, which enable resilience to biotic and abiotic perturbations. At the strain level, we consider the preservation and diversification of adaptive information in progeny lineages. At the community level, we consider genetic exchange between distinct microbes in the ecosystem. Finally, we frame microbiomes as open systems subject to acquisition of novel information from foreign ecosystems through invasion by outsider microbes.

  • Bacterial pathogens accumulate mutations to compete with resident microbiome and host factors when entering the host intestines.

    “Extensive studies proved bacterial pathogens accumulate mutations to compete with resident microbiome and host factors when entering the host intestines.23,24”

    From Gut microbiota drives structural variation of exogenous probiotics to enhance colonization (2025) · cites this paper as [24]

    The review’s “Pathogen evolution during infection” section reports adaptive mutations in pathogens during infection, while “Evolution in gut bacterial populations” describes mutations in E. coli introduced into mouse guts. It does not establish that bacterial pathogens entering the intestines accumulate mutations specifically to compete with both resident microbes and host factors; the cited pathogen examples concern cystic-fibrosis infections.

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.
