Comparison of inflammatory cytokine mRNA levels between different wound types.

Polybacterial wounds containing S. aureus mutant (MT) revealed a significantly decreased level of IL-1β (A) and TNF-α (B) expression relative to polybacterial wild-type (WT) wounds containing UAMS-1 and PAO1. The expression level S. aureus MT-containing polybacterial wounds were of similar magnitude to single-species WT wounds. (*p<0.05, **p<0.01, ***p<0.001) (n = 8–10 wounds/group).
