Characterization of the mechanisms of fluoroquinolone resistance in vancomycin-resistant enterococci of different origins.

Journal of chemotherapy (Florence, Italy) - 1 Apr 2011

López M, Tenorio C, Del Campo R, Zarazaga M, Torres C

Abstract excerpt

The mutations in gyrA and parC genes were analyzed in 22 vancomycin-resistant enterococci of different origins and species, which had varying susceptibility to ciprofloxacin (minimum inhibitory concentration, MIC: 0.5- >256 mg/l). All vanA or vanb2-containing strains with ciprofloxacin MIC of >32 mg/l presented amino acid changes in GyrA protein (S83I, S83Y, S83R or S83I-E87G) with/without changes in ParC protein...
