Hemolytic activity and antibiotic susceptibilities of LA-S. aureus and CA-MRSA. Hemolysis and antibiotic susceptibility testing results are shown for each S. aureus isolate Hemolytic activity was measured as a binary variable, and defined as the formation of a zone of hemolysis after 24 hours of growth on blood sheep agar. MRSA was defined as cefoxitin or oxacillin resistant or positive for the mecA or mecC gene. MDRSA was defined as resistant or intermediate to at least three classes of antibiotics. For the hemolytic, MRSA, and MDRSA categories, black = positive and white = negative. For antibiotic susceptibility categories, black = resistant, grey = intermediate, and white = susceptible. Note. AMP = ampicillin, PEN = penicillin, ERY = erythromycin, CLIN = clindamycin, MOXI = moxifloxacin, TET = tetracycline, TRI/SUL = trimethoprim/sulfamethoxazole, GEN = gentamicin, CEFO = cefoxitin, OXA = oxacillin, MINO = minocycline, NIT = nitrofurantoin, RIF = rifampicin, LIN = linezolid, DAP = daptomcyin and VAN = vancomycin.
