Data are given only for those antibiotics for which a change in the MIC could be detected; only negative MIC changes are displayed.
Maximum growth rate of the mutant growth control relative to the growth of the wild type.
Retesting by agar dilution was performed using antibiotics of the same class: PIP for β-lactams (SAM), MEM for carbapenems (ETP), CAZ for cephalosporins (CAZ), CIP for quinolones (LVX, NAL), and TET for tetracyclines (TGC). SXT was not retested by agar dilution.
The MIC for the wild-type PA14 strain was above the calling range (Fig. 1); the MIC change was calculated based on an assumed MIC for the wild type of twice the upper limit of the calling range.
No PAO1 transposon mutant available. —, no PAO1 ortholog.
MIC change consistent with agar dilution testing of the PA14 mutant using an antibiotic of the same class.
MIC change consistent with agar dilution testing of the PAO1 mutant using an antibiotic of the same class.
