FIG 2.

There is no difference in PDI susceptibility between parental and hypermutator strains. PDI was performed on S. aureus strains HG003 (A) and HG003ΔmutSL (B). Data were collected from three independent experiments performed in duplicate. Error bars represent standard deviations (SD). Statistical differences were determined by an unpaired, two-tailed t test. ***, P = 0.004 (HG003 MB+L− versus MB+L+); **, P = 0.002 (HG003ΔmutSL MB+L− versus MB+L+); ns, not significant (P = 0.556) (HG003 MB+L+ versus HG003ΔmutSL MB+L+).
