Fluoroquinolone resistance in Streptococcus pyogenes has been reported only anecdotally, but a recent Belgian surveillance study found a rate of nonsusceptibility of 5.4%. From an analysis of these isolates, we show that interspecies horizontal gene transfer within the parC quinolone resistance-determining region is a frequent phenomenon that might contribute to fluoroquinolone resistance.
仅偶有关于化脓性链球菌对氟喹诺酮耐药的报道,但最近一项比利时的监测研究发现其不敏感率为5.4%。通过对这些分离株的分析,我们发现parC喹诺酮耐药决定区域内的种间水平基因转移是一种常见现象,这可能导致了对氟喹诺酮的耐药性。
