Fluoroquinolone Resistance in Haemophilus influenzae Is Associated with Hypermutability

Fluoroquinolone Resistance in Haemophilus influenzae Is Associated with Hypermutability Fluoroquinolone-Resistant Mutants ofBurkholderia cepacia Complex Ciprofloxacin Resistome Revealed by Screening a Pseudomonas aeruginosa Mutant Library for Altered Susceptibility Mechanisms Accounting for Fluoroquinolone Resistance in Escherichia coli Clinical Isolates Fitness Costs and Stability of a High-Level Ciprofloxacin Resistance Phenotype in Salmonella enterica Serotype Enteritidis: Reduced Infectivity Associated with Decreased Expression of Salmonella Pathogenicity Island 1 Genes Contribution of Target Gene Mutations and Efflux to Decreased Susceptibility of Salmonella enterica Serovar Typhimurium to Fluoroquinolones and Other Antimicrobials Fluoroquinolone Enhances the Mutation Frequency for Meropenem-Selected Carbapenem Resistance in Pseudomonas aeruginosa , but Use of the High-Potency Drug Doripenem Inhibits Mutant Formation Mutant Selection Window and Characterization of Allelic Diversity for Ciprofloxacin-Resistant Mutants of Rhodococcus equi Influence of High Mutation Rates on the Mechanisms and Dynamics of In Vitro and In Vivo Resistance Development to Single or Combined Antipseudomonal Agents Reduced Susceptibility of Haemophilus influenzae to the Peptide Deformylase Inhibitor LBM415 Can Result from Target Protein Overexpression Due to Amplified Chromosomal def Gene Copy Number
