Objective: The aim of the study was to determine the impact of increasing doses of 2 prebiotic oligosaccharides and of an “all-human diet” on the intestinal microbiota of premature infants.

Methods: Twelve premature infants receiving formula feedings were randomly assigned to receive either galacto-oligosaccharide (F+GOS) or a pooled concentrated donor human milk product containing human milk oligosaccharides (F+HMO) in increasing doses during a 5-week period. A second group of 15 premature infants received their mother's own milk fortified with either a concentrated donor human milk product (H+H) or a bovine powdered fortifier (H+B). Serial stool specimens from each infant were analyzed by terminal restriction fragment length polymorphism and quantitative polymerase chain reaction for bacterial composition.

Results: All of the infants studied had relatively low levels of bifidobacteria and no measurable Lactobacilli. Infants from the F+GOS and F+HMO groups demonstrated an increase in relative numbers of Clostridia with increasing doses. Compared with the H+B group, the infants in the F+HMO and the H+H groups showed an unexpected trend toward an increase in γ-Proteobacteria over time/dose. Principal coordinate analyses and Shannon diversity scores were not significantly different among the 4 groups. Infants in the H+H group received more antibiotics during the study period than those in the other groups. Two of the infants receiving GOS developed feeding intolerance.

Conclusions: None of the prebiotic interventions resulted in significant increases in bifidobacteria compared with baseline specimens or the H+B group; however, many of the infants did not receive the highest doses of GOS and HMO, and antibiotic use in the H+H group was high.
