a Representative abscesses on day 2 after infection (4 isolates were randomly selected/lineage). Each mouse (one mouse/isolate) received 5 × 107 CFUs on the right dorsum by intradermal injection. Control animals (n = 4) received only sterile PBS. b Abscess areas (=π (length × width)/2) on day 2 after infection. c, d Quantitative RT-PCR analysis of RNAIII and hla gene expression in randomly selected ST188 (10 isolates were randomly selected), CA-MRSA USA300(ST8), HO-MRSA ST398, and HA-MRSA ST239 (4 isolates were randomly selected/lineage), from cells grown to the late logarithmic growth phase (4 h). **, P < 0.01; ***, P < 0.001; NS, not significant (P ≥ 0.05)
