Caesarean prevents babies from receiving good bacterial infections from the mother for their immune system, according to study



Scientists at the Biomedicine Center of Systems of Luxembourg have shown that during a natural vaginal part, the specific bacteria of the mother's intestine are transmitted to the baby and stimulate their immune responses. However, this phenomenon does not occur in cesarean-born children.

"This can explain why, by epidemiologically speaking, the cesarean-born children suffer more chronic diseases related to the immune system, compared to infants born vaginal," says Paul Wilmes, head of the study published at the magazine & # 39; Nature Communications & # 39 ;.

Humans are born free of germs. However, birth is usually the time when vital vitamin bacteria begin to colonize the body, including the intestine, skin and lungs. Researchers have long suspected that this early colonization establishes the line for subsequent health. However, according to the conclusion of this study, it could be that a c-section prevents certain bacteria, which usually interact with the baby's immune system, from mother to baby.

Wilmes, along with colleagues from Sweden and other researchers in Luxembourg, found the first evidence of this fact in a baby study, half of whom were born by cesarean section. "We find specific bacterial substances that stimulate the immune system in new born babies. In contrast, the immunological stimulation in children with cesarean section is much lower, as bacterial triggers are present at much lower levels or Other bacterial substances hinder this initial immunity, "the researcher said.

This bacterial colonizing-immune system bond, along with other factors, could explain why cesarean-treated babies are statistically more likely to develop allergies, chronic inflammatory diseases and metabolic diseases. "It could be that the immune system of these children is altered from the beginning," suggests Paul Wilmes.

Now, researchers want to investigate this link more thoroughly and find ways to replace missing mother bacterial strain in newly born cesarean, for example, administering probiotics. "It is clear that we should not intervene very strongly in the part process. Babies should only be treated by caesarean section when medically necessary. We need to be aware that by doing so, we are apparently massively intervening in the natural interactions between humans and bacteria, "he concludes.
