Increased ILA production in fecal samples from infants with high levels of bifidobacteria. Determination of microbiota in infant fecal samples using 16S, Bif-TRFLP, and BLIR assays. a Fecal samples showed low and high distributions of Bifidobacterium among breast fed infants (n = 18) previously characterized (1). In fecal samples with a high level of Bifidobacterium, the distribution of species and subspecies is shown in different shades of green (note B. longum subsp. infantis dominating all of the high Bifidobacterium feces). b PCoA plots of weighted and c unweighted β diversity was significantly different between high and low Bifidobacterium groups. d Metabolite analyses of infant fecal samples by LC-MS/MS (72). e High Bifidobacterium samples showed highly significant differences in ILA production (p < 0.0001) compared to low Bifidobacterium samples. Student t-test was used to determine significance with corresponding P values considered statistically significant in *p < 0.05, **p < 0.01, *** p = 0.0001
