The study identifies several β-lactam resistance genes, including ampC, lacA, pbp2, pbp3, pbp4a, pbp6a, and pbp7, as well as multidrug efflux pumps such as acrAB-tolC, acrAD-tolC, mdtABC-tolC, emrAB-tolC, mexAB-oprM, and others. Additionally, genes like bacA, ksgA, crcB, and rarD are implicated in resistance to bacitracin, kasugamycin, streptomycin, camphor, and chloramphenicol, respectively.
