E. faecalis CRISPR variants change frequency within the E. faecalis population over the colonization period for Infant 2. The relative abundances of each CRISPR variant (diagrammed in Fig. 6) are shown. Additionally, two single nucleotide variants within E. faecalis correlated significantly with CRISPR variant frequencies (Pearson correlation with Bonferroni correction, P < 0.01). Both variants are located in the coding regions of hypothetical proteins.
