- Consider the photos here which demonstrate antibiotic sensitivities of Staphylococcus aureus strains as determined by the Kirby-Bauer method. Abbreviations are as follows: C = chloramphenicol; CC = clindamycin; CZ = cefazolin; E = erythromycin; NOR = norfloxacin; OX = oxacillin; P = penicillin; RA = rifampin; SAM = sulbactam-ampicillin; SXT = sulfatrimethoprim; TE = tetracycline; VA = vancomycin.
