The absence of good intestinal bacteria in babies increases the risk

“The composition of the intestinal microbiota of children is essential to immune development”, According to American researchers. Nevertheless, Indeed, bifidobacteria are among the first beneficial bacteria to colonize the human intestine. Consequently, Their presence has been associated with positive health effects, including protection against metabolic diseases, gastrointestinal infections and inflammation. Problem: few exhaustive assessments on this subject have been carried out. This is why the latter conducted a study, the absence good intestinal bacteria babies results of which were published in the journal Communications Biology.

1 in 4 baby is without healthy intestinal bacteria – Absence good intestinal bacteria babies

As part of the work, the team analyzed the intestinal microbiota of 412 babies, selected to represent the demographic diversity of the United States. The delivery and food mode has been taken into account. The data highlighted a generalized deficit in bifidobacteria in young patients. “About 25 % of American children were devoid of detectable bifidobacterium.” This lack of good intestinal bacteria in infants could contribute to the development of atopy. a genetic predisposition to allergies and asthma.

The method of childbirth, namely by cesarean or low, breastfeeding or the use of artificial milk, as well as exposure to antibiotics can influence the diversity of the intestinal microbiota of toddlers. In detail, the deficiency in bifidobacteria was more pronounced during cesarean deliveries (35 %) than during low -way deliveries (19 %). absence good intestinal bacteria babies In children born by Cesarean. beneficial bacteria were often replaced by potentially pathogenic bacteria, known to eliminate the oligosaccharides from breast milk, components that shape the infant’s intestinal microbiota.

The presence of bifidobacteria is linked to fewer genes resistant to antimicrobials

Another observation: “Microbiota rich in bifidobacterium have distinct characteristics of those with other dominant microbial compositions, including a decrease in antimicrobial resistance genes and virulence factors, alteration of the paths of use of carbohydrates and a modification of metabolic signatures.” In the conclusions. the authors indicate that the absence of these key strains of bifidobacterium represents a real “dysbiosis” or an “imbalance in the microbiota”, the term of which is still debated, at the beginning of life.
