Time-course release of calcein-AM by A. actinomycetemcomitans cells treated with various concentrations of highbush blueberry PACs. Chlorhexidine (200 μg/ml) was used as a positive control. A significant (p < 0.01) release of calcein-AM was observed with PACs at 62.5, 125, and 250 μg/ml following a treatment of bacteria for 120 min. To obtain the same significance, a treatment of 160 min was necessary when PACs were used at 31.25 μg/ml
