FIG. 5.

Opsonophagocytic killing of several staphylococcal strains with MAb F598 at 12 μg/ml. Bars represent means; error bars represent the standard errors of the means. S. aureus strains Mn8, Newman, 10833, and Reynolds and S. epidermidis strain M187 represent methicillin-sensitive clinical and laboratory isolates. Strain 123 (also designated MW2 or USA400) is an MRSA strain carrying the PVL genes whose genome has been sequenced. Strains 192 and 193 represent MRSA, PVL-positive isolates from community-acquired infections. Strain 157 is a methicillin-sensitive, PVL-positive S. aureus isolate from a patient with lethal necrotizing pneumonia.
