In vitro killing of MRSA strain USA300 LAC (A) and P. aeruginosa strain PA01 (B). Bacteria were cultured in lysogeny broth (LB) at 37 °C overnight and then washed with PBS. Bacteria were then incubated with RPMs for 10 min at 37 °C, serially diluted with PBS, and plated on LB (MRSA) or Pseudomonas isolation agar (PA01). Colonies were counted after overnight incubation at 37 °C, and data were log-transformed. Error bars represent SD for n = 3 from a typical experiment performed independently three times. Significance was determined with ANOVA and Tukey HSD. *p < 0.05; **p < 0.01 significance compared to control; data without symbols are not significantly different.
