Recent advances of intestinal microbiota transmission from mother to infant

[Display omitted] •The intestinal microbiota of infants plays an important role in the early life.•Mother transmits the intestinal microbiota to infant in many ways.•This paper reviewed the latest findings in gut microbiota of mother and infant.•This essay provides new ideas for the establishment of infant intestinal microbiota. The intestinal microbiota of infants plays an important role in early life and affects health throughout lifespan. The mother is closely associated with the infant microbiota, by helping to establish it through her own gut microbiota, intrauterine and birth canal environments, and feeding. In this study, the characteristics, influencing factors, and effects of pregnant women on offspring, the establishment and development of intestinal microbiota in infants, and the significance of mother-to-infant transmission were reviewed, to provide new research impetus on the establishment of intestinal microbiota in infants.
