Abstract
One hundred sixteen unrelated clinical isolates of Staphylococcus aure us (70 ciprofloxacin resistant and 46 ciprofloxacin susceptible) from eight countries were studied for the presence of mutations in the grlA , grlB, gyrA, and gyrB gene loci. Two mutations within grlA (located a t codons 80 and 84) and two mutations within gyrA (located at codons 8 4 and 88) were clearly associated with ciprofloxacin resistance, altho ugh other mutations detected within the four genes studied may also co ntribute to decreased susceptibility.
