In a previous study of 24 healthy women,
vaginal microbiome composition became less diverse between the second and third trimesters of pregnancy and just before delivery was enriched with Lactobacillus species, likely contributing to vertical transmission of these bacteria
during vaginal birth.21 In a study of 10 newborns in Venezuela, within hours of delivery, the intestinal tracts of
infants born vaginally were colonized by Lactobacillus and Prevotella, whereas
infants delivered operatively acquired bacteria present on the mother's skin and the hospital environment, such as Staphylococcus, Proprionibacterium, and Corynebacterium.15 Quiz Ref ID Our findings, based on a large group of 6 - week - old
infants, indicated that Lactobacillus also contributes to the microbial environment of the gut but to a lesser extent than Bifidobacteria, Bacteroides, and Streptococcus.

during vaginal birth is higher for mothers and
infants if the mother previously had a cesarean delivery, a new study reports.
