Evidence of Bacterial Biofilms among Infected and Hypertrophied Tonsils in Correlation with the Microbiology, Histopathology, and Clinical Symptoms of Tonsillar Diseases
Figure 4
Microscopic evidence of bacterial biofilms within the tonsillar crypts via CLSM. (a) Representative image of biofilm from a patient with obstructive sleep apnea showing bacterial cells (red) embedded with glycocalyx (green) surrounding the tonsillar nuclei (red). (b) Three-dimensional image of a biofilm showing bacterial aggregates (cells) embedded in a glycocalyx matrix (100x). Arrows indicate the biofilm structures and tissue sections were stained with propidium iodide and concanavalin A.
