Microbiome inheritance and variability

Intrauterine development is accompanied by the absolute sterility of the fetus, which for the first time receives microbiota, overcoming the birth canal during natural childbirth. Therefore, babies born naturally have a more diverse microbiota than those extracted by caesarean section. Also, studies have shown that babies born by cesarean have a greater risk of obesity. Nevertheless, the composition of the microbiota in these children is gradually normalizing under the condition of breastfeeding, which ensures the dominance of bifidobacteria and lactobacilli, which suppress populations of opportunistic bacterioids and clostridia.

Natural birth and breastfeeding form the backbone of the microbiota, which usually lasts for life. Further enrichment of the microbiota with other types of bacteria depends on the lifestyle.

So, for example, visiting kindergarten is a significant and independent factor in increasing the species diversity of the microbiota. On the other hand, the widespread use of antibiotics and antiseptics, as well as strict sanitary and hygiene standards, reduce the intensity of microbiota exchange between people and its diversity. Thus, we can talk about the heritability and variability of the microbiome.Поділитися цим:
