Assesment of the Resistance of Clinical Isolates Pseudomonas Aeruginosa to Quinolonones

Abstract: Thirty multidrug-resistant P.aeruginosa strains, isolated from clinical samples during 2011-2012, were investigated for the mechanisms' of resistance determination to quinolones. It is the first report in Bulgaria regarding the detection of point mutations in the quinolone resistance-determining regions of gyrA and parC as well as for the efflux pomp regulatory mexR genes by the Sanger sequencing method. Mutations, related to quinolone resistance were detected in codon 83 of gyr A gene, codons 87 and 136 of th… Show more
