Bacterial counts from mouse abscesses induced with PVL+ and isogenic ∆pvl S. aureus strains. (A) Comparison of the bacterial counts in 72-h-old abscesses in the skin of mice induced by four wild-type MRSA strains (NRS193, NRS194, LAC, and MW2) with their respective isogenic pvl counterparts. (B) Comparison of bacterial counts from mouse abscesses induced with two wild-type S. aureus strains (NRS193 and LAC) and their isogenic pvl strains at different skin sites within the same mouse. P values are from unpaired t tests. Bars represent means; error bars represent SEM.
