Figure 1 Timed kil curves. A, tPMP-1—susceptible strain ISP479C against vancomycin. B, tPMP-1—resistant strain ISP479R against vancomycin. Solid lines, growth control in Mueler-Hinton broth (MHB); dashed lines, vancomycin-containing media.

Figure 2 Effect of vancomycin preexposure on subsequent tPMP-1—induced killing of tPMP-1—susceptible strain ISP479C over range of peptide concentrations (0.004–2.5 µg/mL). Open bars, killing by tPMP-1 alone (no vancomycin preexposure); closed bars, killing by tPMP-1 after 1-h pre-exposure to vancomycin. Bars are mean log<sub>10</sub> cfu/mL of 3 independent runs.
