Expression of asp23 (A), sarA (B), sae (C), and cap5 (D) in clinical persistent methicillin-resistant Staphylococcus aureus (MRSA) bacteremia (PB) strains (underlined) and resolving MRSA bacteremia (RB) strains after incubation for 6 hours by flow cytometry. Relative fluorescence units (RFU) were used to measure green fluorescent protein (GFP) expression. Cells with >10 RFU were demonstrated as positive for GFP expression. The percentage of GFP-positive cells from each group was analyzed. The results are representative of flow cytometry data in histograms from 1 replicate.
