FIG 4.

Analyses of microbial diversities of 17 pairs of swab-resuspended broth and enriched cultures treated with PBS and EG-LYS. (A) Differences in alpha diversity of Shannon index metric between before and after enrichments by PBS and EG-LYS treatments. No significant difference between EG-LYS and PBS treatments was observed. (B) Changes in microbial community structures following enrichment cultures between PBS and EG-LYS treatments. Weighted and unweighted UniFrac distances are shown on the left and right, respectively. Statistical analysis was conducted by Wilcoxon signed-rank test. Statistical significance is denoted by an asterisk (*, P < 0.05).
