Abstract

Human milk is a rich source of nutrients and energy, shaped by mammalian evolution to provide all the nutritive requirements of the newborn. In addition, several molecules in breast milk act as bioactive agents, playing an important role in infant protection and guiding a proper development. While major breast milk nutrients such as lactose, lipids and proteins are readily digested and consumed by the infant, other molecules, such as human milk oligosaccharides and glycosylated proteins and lipids, can escape intestinal digestion and transit through the gastrointestinal tract. In this environment, these molecules guide the composition of the developing infant intestinal microbiota by preventing the colonization of enteric pathogens and providing carbon and nitrogen sources for other colonic commensals. Only a few bacteria, in particular Bifidobacterium species, can gain access to the energetic content of milk as it is displayed in the colon, probably contributing to their predominance in the intestinal microbiota in the first year of life. Bifidobacteria deploy exquisite molecular mechanisms to utilize human milk oligosaccharides, and recent evidence indicates that their activities also target other human milk glycoconjugates. Here, we review advances in our understanding of how these microbes have been shaped by breast milk components and the strategies associated with their consumption of milk glycoconjugates.

Claims other papers make about this one

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

  • Infants fed formula supplemented with B-GOS had increased abundance of Bifidobacterium and Lactobacillus compared to unsupplemented infants, similar to breastfed infants.

    “Infants fed formula supplemented with Bimuno-galactooligosaccharide (B-GOS®; Bimuno™, Clasado Biosciences Ltd, Buckinghamshire, UK), a proprietary product containing at least 65% GOS, had increased abundance of Bifidobacterium and Lactobacillus compared to unsupplemented infants, similar to levels reported in breastfed infants (Garrido et al., 2013;Vandenplas et al., 2014).”

  • B. infantis is able to produce extracellular glycosidases that allow it to cleave and consume these glycan moieties.

    “However, B. infantis is able to produce extracellular glycosidases that allow it to cleave and consume these glycan moieties [45, 92].”

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.
