A Results of the 96-microtiter plate method for biofilm assay of representative weak, medium, and strong biofilm-producing isolates. B and C Are microscopic observations of the isolates using a bright field light microscope at a magnification of 100 × and 400 ×. D Represents the SEM micrographs of biofilms at 2000×magnification. E and F Are CLSM micrographs of the acridine orange-stained biofilms in two-dimensional perspective and three-dimensional perspective (side view), respectively. Scale bars represent 20 μm for SEM images and 50 μm for CLSM images
