Abstract | | | | Background: Pregnancy is an admirable biological process, resulting in significant changes in many of the body's normal systems so that they can support the development of the fetus. These changes involve hormonal changes, weight gain, immune system regulation, and others that need to be synchronized to maintain both maternal and fetal health. Objective: The purpose of this study was to compare gut microbiome in neonates born by caesarean section and vaginal seeding with gut microbiomes of neonates born by caesarean section without vaginal seeding and neonates born by vaginal delivery. Methods: In Democritus University of Thrace, from 2019 to 2022, gut microbiomes were compared for three groups of neonates. Group A included 110 neonates born by CS who underwent vaginal seeding, group B included 85 neonates born by CS without vaginal seeding and group C included 95 neonates born by vaginal delivery. Results: Vaginal seeding in neonates born with CS resulted in gut microbiome which was similar to the gut microbiome of neonates born by vaginal delivery (including lactobacillus species and bacteroides). On the contrary, gut microbiome of neonates born by CS without vaginal seeding was “limited”. Conclusion: According to our findings, vaginal seeding alters the gut microbiome of the neonates born with CS. However, there is a need for further investigation to prove its efficacy and its safety for the neonate.
Key words: term pregnancies, caesarean section, vaginal delivery vaginal seeding.
