Scientists at the Center for Biomedical Systems in Luxembourg have shown that during the natural vaginal delivery of specific bacteria in the mother's intestine, they transmit the baby and stimulate the immune response. However, this phenomenon does not occur in children born from the imperial section.
"This could explain why, epidemiologically, babies born of the cervix cut more chronic illnesses associated with the immune system compared to babies born vaginal," explains Paul Wilmes, lead study published in the journal Nature Communications.
People were born without germs. However, birth is usually the time when vital bacteria begin colonizing the body, including the intestines, the skin and the lungs. Researchers have long suspected that this early colonization sets a line for later health. However, as this study concludes, it could happen that the cannula cut prevents some bacteria that normally interact with the immune system of the baby from the mother to the newborn.
Wilmes, together with colleagues from Sweden and other researchers from Luxembourg, found the first evidence of this fact in the study of newborns, half of which was born in a cesarean section. "We have specific bacterial substances that stimulate the immune system in vaginal birth babies." In contrast, immunological stimulation in children with carcass cut is considerably smaller, since bacterial agents are present at much lower levels or other bacterial agents they prevent this initial immunity, "the researcher details.
This linkage of bacterial colonization immunity, together with other factors, could explain why cephalopod babies are statistically prone to develop allergies, chronic inflammatory diseases and metabolic diseases. "It could happen that the immune system of these children has changed from the very beginning," suggests Paul Wilmes.
Now, researchers want to further explore this connection and find ways to replace the lack of bacterial strains of mothers in babies born in imperial cuts, for example, by administering probiotics. "It is clear that we should not intervene intensively in the process of giving birth, babies should only be delivered to the imperial route when it is medically necessary." We must be aware that we have, obviously, intervened massively in natural interactions between humans and bacteria, "he concludes.
