Mutant prevention concentration of orbifloxacin: comparison between Escherichia coli Pseudomonas aeruginosa and Staphylococcus pseudintermedius of canine origin

摘要

BackgroundThe mutant prevention concentration (MPC) is an important parameter to evaluate the likelihood of growth of fluoroquinolone-resistant mutants for antimicrobial-pathogen combinations. The MPCs of fluoroquinolones for different canine pathogens have not been compared. In this study, we compared for the first time orbifloxacin MPCs between susceptible strains of Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus pseudintermedius of canine origin.
