Learning Objectives

Each objective describes an AST bench competency, method, QC, and category assignment, not antimicrobial selection or dosing.

Group major antimicrobial mechanisms of action (cell wall, protein synthesis, nucleic acid, membrane, folate pathway) for AST panel literacy
Connect mechanism families to typical phenotypic readouts (zone/MIC behavior) without selecting therapy
Explain how inoculum, media composition, and reading rules can alter apparent activity even when mechanism knowledge is correct
