THE UTILITY OF NON-BETA-LACTAM ANTIMICROBIAL MICS AS MARKERS TO DISTINGUISH OXACILLIN-RESISTANT FROM OXACILLIN-SUSCEPTIBLE STRAINS OF STAPHYLOCOCCUS-EPIDERMIDIS
Rj. Fass et al., THE UTILITY OF NON-BETA-LACTAM ANTIMICROBIAL MICS AS MARKERS TO DISTINGUISH OXACILLIN-RESISTANT FROM OXACILLIN-SUSCEPTIBLE STRAINS OF STAPHYLOCOCCUS-EPIDERMIDIS, Diagnostic microbiology and infectious disease, 26(1), 1996, pp. 43-45
Among 6,068 strains of Staphylococcus epidermidis, 75.5% were oxacilli
n-resistant. Oxacillin-susceptible strains were more frequently suscep
tible to erythromycin, clindamycin, ciprofloxacin, trimethoprim/sulfam
ethoxazole, gentamicin, and tetracycline than oxacillin-resistant stra
ins. With the exception of erythromycin, non-beta-lactam MICs were les
s discriminatory for identifying oxacillin-resistant strains with oxac
illin MICs greater than or equal to 2 mu g/ml than for those with oxac
illin MICs greater than or equal to 4 mu g/ml. (C) 1996 Elsevier Scien
