∗The MAR index of an isolate is defined as a/b, where a represents the number of antimicrobials to which the isolate was resistant and b represents the number of antimicrobials to which the isolate was subjected.
S. aureus strains ATCC WB81 (sea), ATCC 13563 (sed), and ATCC 27664 (see) showing a MAR index of 0.5 and S. aureus strains ATCC14458 (seb) and ATCCWB72 (sec) and S. xylosus ATCC 29971 showing a MAR index of 0.3 were used as reference strains.
CPM: cefepime, CFO: cefoxitin, CLO: chloramphenicol, CIP: ciprofloxacin, CLI: clindamycin, ERI: erythromycin, GEN: gentamycin, NEO: neomycin, LZD: linezolid, RIF; rifampicin, TET: tetracycline, OXA; oxacillin, PEN: penicillin, SXT: sulfamethoprim, and VAN: vancomycin.
