Evidence of Bacterial Biofilms among Infected and Hypertrophied Tonsils in Correlation with the Microbiology, Histopathology, and Clinical Symptoms of Tonsillar Diseases

Figure 3

Microscopic evidence of bacterial biofilms on the tonsillar surface via SEM. (a) Overall image of biofilm from a patient with recurrent tonsillitis showing the layers of network-like glycocalyx (low magnification 1500x). (b) Representative image of biofilm from a patient with chronic tonsillitis showing bacterial cells attached to the surface of tonsillar cells and embedded in a network-like glycocalyx (high magnification 25000x). Arrows indicate the biofilm structures.
