WT S. aureus and ettA^stop demonstrate similar beta-lactam–induced killing dynamics. Cefazolin 16XMIC was added to WT and ettA^stop S. aureus cultures grown to OD600 of 0.2. Broths (sextuplets) were plated for CFU counts at timely intervals. Graph shows mean and SEM for each time point. Paired t-test noted non-significant difference between strains (p = 0.38). Similar results were noted in repeated experiments
