Abstract
The proportion of gyrA and gyrB mutations in quinolone-resistant Escherichia coli strains was examined by introducing cloned wild-type gyrA and gyrB genes. In 25 spontaneous mutants of strain KL16, 13 had gyrA and 12 had gyrB mutations. In eight clinical isolates, five had gyrA mutations and one had a gyrB mutation; mutations in two isolates remained unidentified.This publication has 13 references indexed in Scilit:
