* TBARS values are expressed in micromoles per 1011 cells. The data shown are means (mean ± SD) of three independent experiments in different batches of urine and LB broth. Differences between means were evaluated for statistical significance using the Tukey's HSD (Honestly Significant Difference) test.
**p values of < 0.05 were considered significant. compared to ABU83972 under the same conditions.
