Maternal gut microbiota transmission and early-life colonization patterns influence infant CMPA risk

The establishment of intestinal flora in early life is essential for the health and development of living organisms. At birth, the newborn has already established an initial gut microbiota with distinct characteristics. The link between the composition of the gut microbiota and immune-related symptoms such as allergies is a hot topic, and it starts to show up early in life. It is helpful to study the characteristics and developing rules of early life intestinal flora by interpreting the characteristics of early life flora, the relationship with maternal flora, the development law with age, and the correlation with feeding patterns and so on. In this study, we presented and compared the gut microbiota of newborns, 3-month-old infants, and their mothers to provide a preliminary understanding of the establishment of early life microbiota and its correlation with allergies.
