Abstract

The phenotypes of allergic airway diseases are influenced by the interplay between host genetics and the gut microbiota, which may be modulated by probiotics. We investigated the probiotic effects on allergic inflammation in A/J and C57BL/6 mice. C57BL/6 mice had increased gut microbiota diversity compared to A/J mice at baseline. Acetate producer probiotics differentially modulated and altered the genus abundance of specific bacteria, such as Akkermansia and Allistipes, in mouse strains. We induced airway inflammation followed by probiotic treatment and found that only A/J mice exhibited decreased inflammation, and the beneficial effects of probiotics in A/J mice were partially due to acetate production. To understand the relevance of microbial composition colonization in the development of allergic diseases, we implanted female C57BL/6 mice with A/J embryos to naturally modulate the microbial composition of A/J mice, which increased gut microbiota diversity and reduced eosinophilic inflammation in A/J. These data demonstrate the central importance of microbiota to allergic phenotype severity. Video Abstract.

  • Probiotic efficacy appears to be strain- and population-specific, with some strains effective in certain patient groups but not in others.

    “Accordingly, probiotic efficacy appears to be strain- and population-specific, with some strains being effective in certain patient groups but not in others [92,93], and there is evidence that probiotics may increase the risk of sensitization in individuals predisposed to allergic diseases [94].”

    From Current Concepts in Probiotic Safety and Efficacy (2026) · cites this paper as [93]

    The Discussion (page unavailable) reports that Bifidobacterium longum 51A reduced allergic airway responses in A/J mice but did not prevent exacerbated inflammation in C57BL/6 mice, supporting host-dependent efficacy. The study tested one probiotic strain in mice; it does not establish differences among probiotic strains or efficacy in particular patient groups. (LLM, conf=0.88)

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.
