ABSTRACT
Two quite different disc contents are used for antimicrobial susceptibility testing of two fluoroquinolone drugs, flumequine and enrofloxacin, in the disc diffusion test, 30 and 5 µg, respectively. Using the SRA method, single-strain regression analysis, we studied the impact of disc content when testing two relevant bacterial species, Aeromonas sobria and Vibrio anguillarum. There were no major differences between the antimicrobial regression lines for the two species. Wild-type strains produced acceptable zones of inhibition over a wide range of disc contents. The flumequine 30 µg disc should be lowered in its drug content. No rational reasons for choosing so different disc contents for the two antimicrobials were apparent. At present, the choice of disc content for new antimicrobials are outside the realm of clinical microbiologists. It is recommended that reference authorities, such as EUCAST, CLSI and USCAST, are consulted for the choice of disc contents in the future.
