Your comment will be reviewed and published at the journal’s discretion. It clsi m45 very important to understand that the provision of this new CLSI guideline does not mean clsi m45 antimicrobial susceptibility testing should be performed on every clinical isolate for the organisms included in MA [ 50 ].

First, an analysis in performed of the MICs of a particular drug with wild-type bacterial isolates that lack clsi m45 drug-resistance mechanisms, as well as of the MICs of the drug with strains that contain known drug-resistance mechanisms that affect the clsi m45 drug class, to assess the impact of m455 drug-resistance mechanism.
