Different breakpoints interpretation yielded distinct resistance rates to moxifloxacin of clinically significant anaerobic bacteria

Abstract

The aim of this study was to describe the differences in antimicrobial susceptibility to moxifloxacin between European Committee on Antimicrobial Susceptibility Testing (EUCAST) and Clinical and Laboratory Standards Institute (CLSI) in anaerobic microorganisms. Overall, resistance to moxifloxacin appears to be high in almost all groups of anaerobes, but enormous differences in susceptibility rates between these two committees could be observed.
