Figure 4. Bacteroides spp.-derived products limit S. Typhimurium growth in vitro.
Medium was supplemented with organic extracts of supernatants isolated from anaerobically grown commensal bacteria. A-B) S. Typhimurium CFU/mL. C) L. monocytogenes CFU/mL. D) Y. pseudotuberculosis CFU/mL. E) C. difficile CFU/mL. All extracts were resuspended at 1X concentration. Data represent 3 independent experiments with 3–5 replicates. Error bars represent the standard error of the mean. Significance was calculated using a two-tailed Mann-Whitney test comparing conditions to LB control; NS: not significant, *: p<0.05, **: p<0.01, ***: p<0.001. Unless noted, conditions are not significant.
