A multiple states metagenomic cross sectional study revealed that the vast majority of American infants showed a significant deficiency in an important bacterial strain essential for human milk utilization and immune system development. The study was conducted on 127 healthy infants aged 0-6 months across five geographically diverse states (California, Georgia, Oregon, Pennsylvania and South Carolina). The aims of the study were: (1) characterize the gut bacterial composition of healthy infants during the 0-6 months; (2) determine the metabolic potential of different gut bacterial enterotypes to utilize Human Milk Oligosaccharide (HMO); and (3) to characterize the signature of Antibiotic Resistant Genes (ARGs) in infants across the five surveyed US states.
Findings from this study found that:
