Fig. (2) CLSM images of biofilms on DBR disc surfaces. Biofilm formation of F. nucleatum ATCC 23726 (A) T. forsythia ATCC 43037
(B) V. atypica PK 1910 (C) K. pneumoniae IA 565 (D) on DBR discs. For each set, the image on the left was taken through a 20x objective
(Scale bar, 50 μm); while the image on the right was taken through a 63x objective (Scale bar, 20 μm). Four random fields of view were examined
for each sample and representative images are shown.
