The effect of JNJ-Q2 (p.o., squares), linezolid (p.o., triangles), and vancomycin (s.c., circles) on acute CA-MRSA (OC 8525) skin infections. Each symbol represents the mean ± standard error for 8 to 20 mice. The starting inoculum was 6.8 log10 CFU/mouse, and untreated control values (48 h) were 8.0 log10 CFU/g skin tissue. The P values were generated by comparing the slopes of the dose-response curves for JNJ-Q2 versus linezolid (P value, <0.0001) and for JNJ-Q2 versus vancomycin (P value, <0.0045).
