Effect of Probiotic Administration During Pregnancy on the Functional Metabolism of Gut Microbiota in Healthy Infants

24 pregnant women were randomly assigned to two groups. The probiotic group consisted of pregnant women who consumed triple viable Bifidobacterium longum, Lactobacillus delbrueckii bulgaricus, and Streptococcus thermophilus tablets from the 32nd week of pregnancy until delivery. The meconium from the newborn, stool on the third day after birth, stool on the 14th day, and stool at six months of age were collected. The functional profiles of the gut microbiota were predicted through high-throughput 16S rRNA sequencing results using PICRUSt software and referencing the KEGG database.
