Twelve antibiotics were used in establishing the level of antimicrobial resistance among the Staphylococcus aureus (1,131 strains) and CNS isolates (608 strains). The antibiotics examined included CEF, cefoxitin (30 μg); CHL, chloramphenicol (30 μg); CIP, ciprofloxacin (5 μg); CLI, clindamycin (2 μg); ERY, erythromycin (15 μg); GEN, gentamicin (10 μg); OXA, oxacillin (1 μg); PEN, penicillin (10 μg); SXT, trimethoprim–sulfamethoxazole (1.25/23.75 μg); TEI, teicoplanin (30 μg); TET, tetracycline (30 μg); VAN, vancomycin (30 μg).

CNS, coagulase-negative staphylococci.
