Effect of Alginate Lyase on Biofilm-Grown Helicobacter pylori Probed by Atomic Force Microscopy

Figure 3

Adhesion force maps of H. pylori biofilm: (a) representative high-resolution image ( μm) of H. pylori before treatment (a) and after treatment with AlgL (d). Representative adhesion force maps ( pixels) with shadows of bacteria (red lines) were shown for H. pylori before treatment (b) and after treatment with AlgL (e). Histograms and Gaussian fit (black lines) obtained from five different maps for H. pylori before treatment (c) and after treatment with AlgL (f).
