The human microbiota is made up of trillions of bacteria, viruses, fungi, and other beneficial and harmful microorganisms that live in and around our bodies. Women naturally provide these pioneer colonists with the sterile bodies of their newborns during childbirth, helping them develop their immune systems. But antibiotics և C արում block the passage of bacteria են are associated with an increased risk of obesity, asthma և metabolic diseases.

During the first year of their lives, the researchers looked at 177 babies from four countries. 98 were born vaginally և 79 were born with C-section, 30 of whom were sprinkled with their mother’s vaginal veil immediately after birth.

Laboratory analysis showed that the C-segment neonatal microbiota, sprinkled with the mother’s vaginal fluids, was close to that of newborns. In addition, the mother’s vaginal microbiome on birth was similar to other areas of their body (intestines, mouth, skin), showing that maternal vaginal fluids help colonize bacteria on their babies’ bodies.

This was it the first major observation study to show that r:The natural effect of the C-section baby on the mother’s vaginal microbes at birth is normalized by the growth of bacteria during the first year of life. The researchers say the next step is to conduct randomized clinical trials to see if normalization of the microbiota turns into disease protection.

“Additional research is needed to find out which bacteria protect against obesity, asthma, allergies, and underlying inflammatory diseases.” said the senior author Maria Gloria Dominguez-Bello, Professor, Department of Microbiology, School of Environmental Biochemistry, School of Biological Sciences, Rutgers University, New Brunswick. “Our findings support the hypothesis that the acquisition of maternal vaginal microbes normalizes the development of neonatal microbiomes.”

According to the World Health Organization, about 15 percent of births require a C-section to avoid endangering the life of the mother or baby, but in many countries, such as Brazil, the Dominican Republic, Iran, and China, C-sections are performed on more than 70 urban births. percent.
