Infant intestinal bacteria or from multiple parts of the mother body

previous studies have suggested that babies are born sterile and that the creation of their gut bacteria is influenced only by bacteria in their surroundings. Reporter November 30 from Inner Mongolia Agricultural University was informed that the university Professor Zhang Peace team under the "mother-to-child bacteria transmission mechanism and correlation research" project through expert acceptance, its research results cracked the mother-to-child bacteria transmission mechanism, or will redefine and explain the origin of human gut microorganisms.Using a combination of three generations of sequencing and microdriver digital PCR (polymerase chain reaction), theteam studied the bacterial structure of mothers and children using 41 pairs of female and child volunteer feces, mother feces, amniotic fluid, breast milk, and maternal saliva samples. The results showed that fetal feces, amniotic fluid and breast milk had the advantage of thick-walled and deformed bacillus, while the mother's feces and saliva had thick-walled bacteria and bacillus as the advantage.Fetal feces and amniotic fluid, birth channel fluid, breast milk cytospheric similarity is significantly higher than other mother-source samples, which indicates that the intestinal bacterial structure of early infants is closely related to the pre-birth living environment (amniotic fluid) and the temporary environment (birth channel) during childbirth, the fetus may be in the womb by swallowing amniotic fluid to obtain the original mother-sourced microorganisms.addition, the team found that lactobacillus was significantly higher in absolute levels of fetal feces in naturally delivered babies than babies delivered by caesarean section. This suggests that different modes of delivery affect the planting of Lactobacillus bacteria in the early intestines of infants, which may be related to the birth pathway of the baby during natural childbirth, which is associated with the transmission of bacteria.The results of the project reveal and prove that baby fetal fecal microorganisms come from multiple maternal sites, of which the amniomic microbiome contributes the most to the fetal fecal microbiome, which provides an important reference for understanding the origin of human gut microorganisms.
