Staphylococcus aureus causes increased pH in lysosomes. (A) Cells stained with 100 nM LysoTracker Deep Red at 37°C for 30 min after S. aureus infection to assess the lysosomal pH. (B) Cells stained with 10 μg/ml acridine orange at 37°C for 30 min. Slides were viewed using a scanning confocal microscope, and representative confocal images were shown. Scale bars: 10 μm.
