Studies have shown that the adult gut microbiota is more stable and has a high degree of similarity between individuals2. In contrast, the infant gut microbiota changes rapidly and fluctuates greatly during development in terms of bacterial abundance, diversity and structure. , is easily affected by factors such as delivery mode, feeding method, complementary food addition, disease and environment. The results of a study of neonatal meconium showed that the initial colonization of the vagina in vaginal infants was positively correlated with their mother’s vaginal and intestinal microbiota (Escherichia coli, Lactobacillus, etc.) The skin microbiota (Corynebacterium staphylococcus and Propionibacterium) was positively correlated and may also be related to the mother’s isolation environment and airborne bacteria. The infants enrolled in this study were all vaginally delivered infants, and a large number of bifidobacteria, Escherichia coli, Enterococcus and Lactobacillus were detected in the fecal microbiota in the early postnatal period, which was consistent with previous studies. The type of feeding established in the early postnatal period is also an important factor affecting the colonization of the neonatal gut microbiota. Current research has confirmed that the immune substances in breast milk can increase the infant’s ability to resist infection, and the bifid factor can promote the proliferation of intestinal bifidobacteria in infants and contribute to the establishment of normal intestinal flora in the early stage. Optimal feeding for the first 6 months. Several studies have shown that breast-fed infants have higher levels of bifidobacteria and lactobacilli in the gut than formula-fed infants, while Bacteroides, Staphylococcus, and Enterobacteriaceae are less abundant. The results of this study showed that there were differences in the structure of the intestinal flora of infants with different feeding methods: the number of bifidobacteria in breast-fed infants and probiotic milk-fed infants showed an increasing trend, and the measured time points were higher than those of ordinary milk-fed infants. The values were also higher than those of regular formula-fed infants, while there was no difference in Bifidobacterium counts and B/E values between breast-fed and probiotic formula-fed infants. This suggests that early addition of probiotics to infant formula improves the structure of the infant’s gut microbiota, making it closer to that of breastfed infants. probioticseverything.com

Koenig et al. tracked the development of the gut microbiota in infants from birth to 2.5 years of age and found that diet had a significant effect on microbial community changes. Breast milk is rich in oligosaccharides that have a strong prebiotic effect on the developing microbiota of the newborn, promoting the growth of Bifidobacterium, Lactobacillus and other initial colonizers of the gut, which contain plants that promote complex Genes for the absorption of polysaccharides allow the infant gut microbiota to digest simple plant foods such as rice before solid foods are added. With the addition of complex foods and infant formula, the Bacteroidetes bacteria in the intestinal tract of infants increased rapidly, and functional genes such as degrading carbohydrates and xenobiotics and synthesizing vitamins appeared. In this study, all three groups of infants received feeding guidance, and complementary foods (rice flour juice, vegetable juice, etc.) were added at the 5th month after birth. The /E value was lower than before, and the reason for the analysis may be that the dietary structure of infants changed after the addition of complementary food, which in turn affected the structure of intestinal flora by interfering with the intestinal microecological habitat. The above changes were more pronounced in ordinary formula-fed infants, possibly due to the presence of more bifidobacteria in the gut of breast-fed infants and probiotic formula-fed infants. Schmidt et al. studied the effect of limiting microbial exposure in the early postnatal period on the development of gut microbiota and found that the establishment and development of normal gut microbiota requires continuous exposure to microbes early in life, and an excessively hygienic environment can impair this process. probioticseverything.com
