Fig 2. Viability of planktonic R6 in PAE-phase.

Cultures containing 10⁸ CFU/ml were exposed for 1 h to the indicated drug concentrations, diluted 1000-fold in drug-free media and incubated during 6 h. (A) Quantification of alive (black bars), damaged (hatched bars), or dead (white bars) bacteria in PAE-phase stained with the BacLight kit and counting by fluorescence microscopy BXG1 (100 bacteria for each condition). (B) Growth kinetics of bacteria in PAE-phase. The results are the mean ± SD of two or three independent experiments.
