Column chart representing the relative E. coli intracellular levels of TMP after challenging with 1 mg/L of the drug compared with the control sample W3110 detected by LC-MS analysis; the relative concentration levels of TMP were normalized to the OD600 readings. Six replicates were used for each strain, and the data represent the mean ± SD from three independent experiments. P values were calculated using t tests (*, P < 0.05; **, P < 0.01; ***, P < 0.001).
