Abstract excerpt
OBJECTIVES: To evaluate the mutant prevention concentrations (MPCs) of ciprofloxacin for two susceptible and one first-step gyrA resistant mutant Escherichia coli strains in an in vitro kinetic model and to identify the pharmacodynamic index that best predicts prevention of resistance emergence. METHODS: An in vitro kinetic model was used to measure MPC with static antibiotic concentrations and to test different...
