Bifidobacteria are among the first colonizers of infant gut, and human milk oligosaccharides (HMOs) in breastmilk instrumental for formation a bifidobacteria-rich microbiota. However, little is known about assembly bifidobacterial communities. Here, by applying theory to community four representative infant-gut associated Bifidobacterium species that employ varied strategies HMO consumption, we show arrival order sugar consumption phenotypes significantly affected formation. bifidum longum subsp. infantis, two avid consumers, dominate through inhibitory priority effects. On other hand, breve, with limited HMO-utilization ability, can benefit from facilitative effects dominates utilizing fucose, an degradant not utilized species.

The infant gut microbiome plays a key role in the healthy development of human organism and appears to be influenced by dietary practices through multiple pathways. First, maternal diet during pregnancy nutrition significantly influence microbiota. Moreover, breastfeeding fosters proliferation beneficial bacteria, while formula feeding increases microbial diversity. timing introducing solid foods also influences microbiota composition. In preterm infants is factors, including time since birth intake breast milk, interventions such as probiotics prebiotics supplementation show promising results reducing morbidity mortality this population. These findings underscore need for future research understand long-term health impacts these further strategies enrich formula-fed infants.

SUMMARY Human milk oligosaccharides (HMOs) are complex, multi-functional glycans present in human breast milk. They represent an intricate mix of heterogeneous structures which reach the infant intestine intact form as they resist gastrointestinal digestion. Therefore, confer a multitude benefits, directly and/or indirectly, to developing neonate. Certain bifidobacterial species, being among earliest gut colonizers breast-fed infants, have adapted functional capacity metabolize various HMO structures. This ability is typically observed infant-associated bifidobacteria, opposed bifidobacteria associated with mature microbiota. In recent years, information has been gleaned regarding how these well certain other taxa able assimilate HMOs, including mechanistic strategies enabling their acquisition and consumption. Additionally, complex metabolic interactions occur between microbes facilitated by utilization breakdown products released from degradation. Interest HMO-mediated changes microbial composition function focal point numerous studies, times fueled availability individual biosynthetic some now commonly included formula. this review, we outline main assimilatory catabolic employed discuss that exhibit glycan degradation capacity, cover HMO-supported cross-feeding related metabolites described thus far.

Human milk oligosaccharides (HMOs) shape the gut microbiota in infants by selectively stimulating growth of bifidobacteria. Here, we investigated impact HMOs on adult and barrier function using Simulator Intestinal Microbial Ecosystem (SHIME®), Caco2 cell lines, human intestinal organoid-on-chips. We showed that fermentation 2’-O-fucosyllactose (2’FL), lacto-N-neotetraose (LNnT), combinations thereof (MIX) led to an increase bifidobacteria, accompanied short chain fatty acid (SCFA), particular butyrate with 2’FL. A significant reduction paracellular permeability FITC-dextran probe was observed monolayers fermented 2’FL MIX, which claudin-8 gene expression as shown qPCR, a IL-6 determined multiplex ELISA. Using gut-on-chips generated from organoids derived proximal, transverse, distal colon biopsies (Colon Intestine-Chips), claudin-5 significantly upregulated across all three following treatment under microfluidic conditions. Taken together, these data show that, addition their bifidogenic activity, have capacity modulate immune barrier, supporting potential provide health benefits adults.

Human milk is the optimal nutrition source for infants, and oligosaccharides represent third most abundant component in after lactose fat. (HMO) are favorable macromolecules which are, interestingly, indigestible by infant but serve as substrates bacteria. Hypothesizing that maternal diet itself might influence HMO composition, we sought to directly determine effect on Employing a human cross-over study design, demonstrate distinct dietary carbohydrate energy sources preferentially alter concentrations of HMO, including fucosylated species. We find significant associations between concentration HMO-bound fucose abundance fucosidase (a bacterial gene digests moieties) harbored These studies reveal successive mechanism during lactation alters turn shapes functional microbiome prior ingestion.

Prebiotic human milk oligosaccharides (HMOs) are found in milk, which not digested by infants but metabolized beneficial gut bacteria. We determined the ability of 57 bacterial strains within Family Lactobacillaceae and genera Bifidobacterium Bacteroides potentially pathogenic bacteria to ferment HMOs 2′-fucosyllactose, 3-fucosyllactose, difucosyllactose. In addition, prebiotic galacto-oligosaccharides (GOS), lactose, fucose, glucose were evaluated as carbon sources for these strains. Bacterial growth was monitored using automatic Bioscreen C system. Only certain bifidobacteria, such longum subsp. infantis bifidum, well fragilis, vulgatus, thetaiotaomicron utilized studied their sole source, whereas almost all able utilize GOS, glucose. The selectivity utilization only can be advantageous promoting microbes supporting harmful pathogens contrast other less selective prebiotics.
