    Title

    The characteristics of the intestinal flora of breast-fed infants and the effect of bifidobacteria on the intestinal barrier intervention

    Summary

    Infancy is a critical period for colonization of intestinal flora.
    The early colonization mode of flora directly affects the intestinal barrier function and immune system development of infants during their growth

    .
    Therefore, we chose the key stage of infancy to analyze the characteristics of the intestinal flora of breastfed infants, explore the relationship between the composition of breast milk and the intestinal flora of infants, and perform whole-genome sequencing and bioinformatics analysis of bifidobacteria from the infant’s intestinal tract In addition, the effect and mechanism of the intervention of two surface proteins of bifidobacteria on the intestinal barrier were explored

    .
    The results showed that the oligosaccharide components in breast milk are beneficial to shape the intestinal flora of infants, mainly bifidobacteria.
    About 11% of the coding genes of bifidobacteria isolated from the intestinal tract of breastfed infants are involved in carbohydrate transport and metabolism.
    Helps bifidobacteria to use oligosaccharides in breast milk

    .
    Bifidobacterium surface protein GroEL and transaldolase can regulate the expression of tight junction related proteins through NF-κB, MAPK, Rho and MLCK signaling pathways, effectively preventing endotoxin-induced inflammation of intestinal epithelial cells
