FIG 1.

Microbial alpha diversity (i.e., within samples) during inflammation (5 days postligation) is greater in S100A9^−/− than WT mice. Alpha diversity is represented by the Shannon index for taxonomic richness and evenness. Greater diversity within the sample constitutes a higher Shannon index value. Significant differences between group means were determined using the Mann-Whitney U test. Swab/ligature comparisons using the Mann-Whitney U test were made pairwise within-mouse. Between-group comparisons are indicated by bars with P values. P values of <0.05 were considered significant (n = 7 to 8 for each treatment group).
