Detection of gyrA and gyrB mutations in quinolone-resistant clinical isolates of Escherichia coli by single-strand conformational polymorphism analysis and determination of levels of resistance conferred by two different single gyrA mutations.

Twelve quinolone-resistant clinical isolates of Escherichia coli (nalidixic acid MICs, 64 to 512 micrograms/ml; norfloxacin MICs, 0.25 to 8 micrograms/ml) were transformed with plasmid pJSW101 carrying the gyrA+ gene and with plasmid pJB11 carrying the gyrB+ gene to examine the proportion of gyrA an...
