Abstract excerpt

A G88C mutation in GyrA is one of the key alterations by which Mycobacterium tuberculosis mutants acquire DC-159a resistance in vitro. A novel double mutation in GyrA, G88C D94H, conferred high DC-159a resistance. Different mutation patterns in GyrA were demonstrated for DC-159a-resistant mutants and quinolone-resistant multidrug-resistant (QR-MDR) M. tuberculosis isolates, with a mutation either at position 90...
