Antimicrobial Susceptibility Breakpoints and First-Step parC Mutations in Streptococcus pneumoniae: Redefining Fluoroquinolone Resistance
|Isolate no.||Amino acid substitution
||Change in MIC with inhibition of efflux|
|In ParC||In GyrA|
aparE and gyrB sequencing was performed on all isolates, but no mutations were found in the quinolone-resistance–determining region.
