WebJun 8, 2024 · For analysis of the relation between antimicrobial susceptibility and mutations in parC, gyrA, or 23S rRNA gene, the MICs of M. genitalium strains were dichotomized at MICs ≥ 1 mg/L for quinolones and macrolides. The presence of mutations in the 23S rRNA gene or the QRDR of parC in relation to resistance was compared by Fisher’s exact test. Weblones was shown to be associated with mutations in the gyrA gene, coding for DNA gyrase, and in the parC gene, coding for DNA topoisomerase,8"11'14 and also with reduced uptake and accumu-lation of fluoroquinolone in the cells.15 gyrA is the primary target in gonococci, with parC changes secondary but associated with high-level QRNG.8'13
