Effect of infant formula with probiotics on intestinal microbiota

Weaning during infancy refers to the initiation of complementary food to breast milk. During weaning, there are significant changes on the gastrointestinal microbiota. Deleterious alterations of the gastrointestinal microbiota can result in pathological processes while measures that stimulate its development and stability, like the use of probiotics, are beneficial. The mechanisms by which probiotics achieve their effects have not been clearly established. Present work compares the microbial composition of feces from infants that were weaned to regular family food, formula with probiotics (B. Lactis BL y S. Thermophilus) or formula without probiotics. Accordingly, analysis of rDNA of microbial fecal samples by…
