FIGURE 2.

Microbiota structure of the infant’s gut and mouth and mother’s milk in moderately preterm infants, in relation to latching. PCoA based on Bray-Curtis distances between genus-level relative abundance profiles of fecal (A), oral (B), and mother’s milk (C) samples. Samples taken before and after latching are depicted as empty dots and filled triangles, respectively. First and second coordination axes, with percentages of plotted variation, are reported as in Figure 1.
