Illuminated TAPP-allograft disperses biofilm. (A) S. aureus AH1710 was allowed to form a biofilm on PBS or TAPP-allograft by incubation for 48 hours in the dark. Bacterial colonization (as a result of expression of GFP) was visualized after another 18 hours in the dark or after illumination (“a” is PBS allograft in the dark or “b” light; “c” is TAPP allograft in the dark or “d” light). Magnification: scale bar = 500 µm. (B) Adherent S. aureus were recovered and counted (shown as CFU/ml) from PBS or TAPP-allograft treated as in Fig. 4A. *p < 0.05 when compared with the other counts as determined by a two-tailed t-test.
