CHL, chloramphenicol; CIP, ciprofloxacin; CLI, clindamycin; ERY, erythromycin; FOX, cefoxitin FUS, fusidic acid; GEN, gentamicin; KAN, kanamycin; LZD, linezolid; MIC, minimal inhibitory concentration; MUP, mupirocin; PEN, penicillin; R, resistance; RIF, rifampicin; SMX, sulfamethoxazole; STR, streptomycin; SYN, quinupristin/dalfopristin; TET, tetracyclin; TIA, tiamulin; TMP, trimethoprim; VAN,vancomycin.
  2. Empty boxes indicate the concentration values that were not tested. Values in grey boxes indicate MIC higher than the concentration tested.
  3. The bold lines indicate epidemiological cut-off values for S. aureus. MIC values were interpreted using the EUCAST clinical breakpoints/epidemiological cut-offs [1].
