Effect of adhesion to salivary proteins on the ATR of different streptococcal (a) and Actinomyces (b) strains. Biofilm cells adhered to salivary protein coated or uncoated surfaces were exposed to an adaptation pH (pH 5.5). Increased acid tolerance (indicating induction of an ATR) was evaluated after an acid challenge (pH 3.5) followed by LIVE/DEAD® BacLight™ staining and CLSM, and expressed as % viability. The graphs show the mean and standard deviation of three independent biological replicates. *P < 0.05, **P < 0.001
