Figure 4.
CLSM images of MRSA ATCC 43300 biofilm treated with/without PYO. MRSA biofilm (24 h old) was exposed for 24 h to different PYO titers (ranging from 0 to 106 PFU/ml) and then stained with WGA488 (488/500–600 nm – blue) for exopolysaccharides and SYTO™85 (561/600–700 nm – green) for bacterial cells. Scale bar: 25 μm.
