Abstract

Summary: Bifidobacterium bifidum is reported to be among the first colonizers of the newborn's gastrointestinal tract due to its ability to metabolize human milk oligosaccharides (HMOs). In order to investigate biological features that allow this bifidobacterial species to colonize a newborn, bifidobacterial internally transcribed spacer profiling of stool samples of 50 mother‐infant dyads, as well as corresponding breastmilk samples, was performed. Hierarchical clustering based on bifidobacterial population profiles found in infant faecal samples revealed the presence of four bifidobacterial clusters or the so‐called bifidotypes. Bifidobacterium bifidum was shown to be a key member among bifidotypes, in which its presence correlate with several different bifidobacterial species retrieved in infant faecal samples. For this reason, we investigated cross‐feeding behaviour facilitated by B. bifidum on a bioreactor model using human milk as growth substrate. Transcriptional profiles of this strain were evaluated when grown on nine specific glycans typically constituting HMOs. Remarkably, these analyses suggest extensive co‐evolution with the host and other bifidobacterial species in terms of resource provision and sharing, respectively, activities that appear to support a bifidobacteria‐dominant microbiome.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • B. bifidum is a relevant member of the human gut microbiota from early life, where it plays a pivotal role in maintaining host homeostasis by modulating immune responses, inhibiting pathogenic organisms, and supporting the structural integrity of the intestinal barrier.

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.
