Core Tip

Core Tip: Gut microbiota in very low-weight preterm infants is characterized by delayed colonization and decreased bacterial species which can lead to complications. In this study, we analyzed it using 16S rRNA gene sequencing in 40 hispanic infants classified into two groups: those receiving breast milk (BM) and those with mixed feeding. A decrease in the counts of Alpha and Betaproteobacteria, with higher counts of bifidobacteria, Bacteroidetes, and Clostridium were observed in the BM group. This study contributes to the literature on the structure of the gut microbial of preterm infants.
