  1. AX = Ampicillin/Cloxacillin; CPM = Cefepime; CPD = Cefpodoxime; CAZ = Ceftazidime; C = Chloramphenicol; MRP = Meropenem; NIT = Nitrofurantoin; P = Penicillin-G; RIF = Rifampicin; S = Streptomycin;VA = Vancomycin. The classes of antibiotics are: Carbapenems (MRP), Cephalosporin (third generation; CAZ), Penicillin (P-G), Beta-lactam (AX), Cephalosporin (third generation; CPD), Phenicol (C), Cephalosporin (fourth generation, CPM), Nitrofurans (NIT), Glycopeptides (VA), Ansamycin (RIF), and Aminoglycosides (S)
  2. The results are depicted by: susceptible (S), Intermediate (I), or resistant (R) to each antibiotic
