Quinolone resistance in clinical isolates of Serratia marcescens.

AUTOR(ES)
RESUMO

The uptakes of norfloxacin by quinolone-resistant and -susceptible strains of Serratia marcescens were almost the same and 50% inhibitory concentrations for DNA gyrase and the MICs of quinolones were correlated, suggesting that DNA gyrase alterations are the basis of quinolone resistance.
