Resistance genes
The 13 antimicrobial resistance genes CORE-ABR applies — mecA, vanA/vanB, CTX-M, KPC, AmpC, OXA, IMP/VIM, qnr, tet, erm, dfrA and sul — with what each removes and spares.

Detection of a resistance gene predicts resistance; absence of a detected gene does not establish susceptibility, because resistance arises through mechanisms outside any panel's target set.
