Breastfeeding is associated with fewer antibiotic resistance genes in babies, according to recent research. The study analyzed the relationship between the type of baby feeding and the presence of antimicrobial resistance genes in their intestinal bacteria.
Antimicrobial resistance is pointed out as one of the main global public health challenges. Although it has been traditionally associated with antibiotic use, intestinal bacteria begin to acquire and establish resistance genes from the very first moments of life.
The researchers found that babies fed with breast milk had a lower amount of these genes compared to babies fed with infant formulas. This discovery suggests that the composition of breast milk may play a protective role in the development of the gut microbiome of newborns.
