Summary

The development of the intestinal microbiome in premature infants affects gut maturity and may mediate the risk for necrotizing enterocolitis.  Dr. Gregory and colleagues demonstrate that preterm infants who receive expressed breast milk have greater initial bacterial diversity and more gradual acquisition of diversity compared to those who receive formula.  Supplementation with pasteurized donor human milk partially promoted a microbiome similar to that of breast-milk fed infants.

Key Findings

Feeding with breast milk appears to have a protective effect against gut immaturity in the preterm infant.
