Abstract

We performed a large-scale genome-wide analysis aiming to investigate the prevalence and strain-level diversity of Bifidobacteriaceae species in the human microbiome. We considered 9,528 publicly available human metagenomes and integrated them with 1,192 isolate genomes from different sources. The prevalence and abundance of Bifidobacteriaceae species in humans was linked to multiple host characteristics: they were reduced in older people and enriched in populations characterized by Westernized lifestyles with geography-specific patterns. Phylogenetic analysis highlighted 110 Bifidobacteriaceae species-level genome bins (SGBs), with 32 found in humans and 8 in food and probiotic sources. Functional annotation revealed a great diversity in carbohydrate-active enzyme families across these SGBs. We found potential subspecies for most of the SGBs prevalent in humans and identified patterns driven by age and geography. We provided evidence that strains used in probiotics were rarely identified in humans, with the only exception represented by Bifidobacterium animalis. We finally evaluated that the abundance of Bifidobacteriaceae species exhibited moderate and variable capabilities to predict health status in case-control studies.

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.
