Fig. 5

a-c Representative image of localization of Bodipy-labelled vizantin (Fluo-Viz) on the cell surface. a Transmission image of glass bottom surface. Almost all adhered cells were cocci (An additional zoom of 3× using a 100× oil-immersion objective lens). Scale bar = 5 μm. b Fluorescence image. Fluo-Viz (green) bound to the bacterial surface. c Higher magnification of the area indicated by the squares in B (an additional zoom of 5×). Arrowheads show the chains of Streptococci. Scale bar = 5 μm. d Hydrophobic property determined using microbial adhesion to hydrocarbon (MATH) test following exposure to 10 or 50 μM of Viz-S for 10 min (n = 6). *p < 0.05, compared with the control
