, 4 Veterinary diagnostic laboratories (VDLs) across the country routinely perform antimicrobial susceptibility testing (AST) on a wide array of samples, and some perform whole genome sequencing (WGS) of pathogens. Several projects currently aggregate

antimicrobial susceptibility testing (AST) methods remain the gold standard. In short, genotypic ART tells you which antimicrobials you cannot use, while AST tells you which are appropriate for use. The purpose of this article is to review genotypic ART through
