Figure 3. CLSM analysis of MRSA biofilms.
MRSA was incubated with different concentrations of berberine (a) control; (b) 4 μg/mL; (c) 8 μg/mL; (d) 16 μg/mL; (e) 32 μg/mL; (f) 64 μg/mL; scale bar = 50 μm. MRSA biofilms were stained with acridine orange, and observed with CLSM at a magnification of 200×.
