Effects of microbiota-directed supplementary foods on gut microbiota in fecal colonized mice of healthy infants

At present, more and more attention has been paid to the gut microbiota of infants. This study comprehensively evaluated the effects of three microbiota-directed supplementary foods on mice. This study detected the immunity indicators in the serum, intestinal permeability, the content of short-chain fatty acids, and the structure of gut microbiota in mice. The results showed the RUSF-2 group showed higher relative abundance of short-chain fatty acid-related microorganisms, Faecalibaculum and Bifidobacterium. Therefore, our research results show that the supplementary food of the RUSF-2 group is most beneficial to the infant immunity and gut microbiota.
