Oxacillin resistance screening agar base for detection of methicillin-resistant Staphylococcus aureus.
In a recent letter, Simor et al. reported results obtained by using oxacillin resistance screening agar base (ORSAB; Oxoid Limited, Basingstoke, England) for the detection of methicillin-resistant Staphylococcus aureus (MRSA) from clinical specimens (A. E. Simor, J. Goodfellow, L. Louie, and M. Louie, Letter, J. Clin. Microbiol. 39:3422, 2001). ORSAB is a modification of a mannitol-salt agar su...
متن کاملComparison of M.I.C.E. and Etest with CLSI Agar Dilution for Antimicrobial Susceptibility Testing against Oxacillin-Resistant Staphylococcus spp
OBJECTIVE The main objective of this study was to comparatively evaluate the performance of M.I.C.E. and Etest methodologies to that of agar dilution for determining the antimicrobial susceptibility profile of oxacillin-resistant Staphylococcus spp. METHODS A total of 100 oxacillin-resistant Staphylococcus spp. isolates were collected from hospitalized patients at a teaching hospital. Antimic...
متن کاملDetection and identification of Staphylococcus lugdunensis are not hampered by use of defibrinated horse blood in blood agar plates.
Staphylococcus lugdunensis is a coagulase-negative staphylococcus with pathogenic properties similar to those of Staphylococcus aureus (4). Identification of S. lugdunensis is not necessarily straightforward, resulting in considerable variation in detection rates in different laboratories. Böcher and coworkers recently published data to increase awareness of this pathogen and described some bas...
متن کاملEvaluation of mannitol salt agar for detection of oxacillin resistance in Staphylococcus aureus by disk diffusion and agar screening.
Mannitol salt agar was evaluated for detection of oxacillin resistance in 136 Staphylococcus aureus isolates. All mecA-positive isolates (n = 54) were correctly categorized as oxacillin resistant by the disk diffusion test (1-microgram disk; zone diameter, < 16 mm); the specificity was 97.6%. Agar screening (2 micrograms of oxacillin per ml) revealed a sensitivity of 98.1% and a specificity of ...
متن کاملPhenotypic Changes of Oxacillin Resistance in Methicillin-resistant Staphylococcus aureus Strains by Successive Passaging
Background and purpose: Rotational use of antibiotics can decrease antibiotic resistance in Staphylococcus aureus strains. The present study aimed to evaluate the alteration of oxacillin resistance in methicillin-resistant Staphylococcus aureus (MRSA) strain carrying SCCmec III cassette in long-term evolutionary experiments in an antibiotic-free medium. Materials and methods: In a cross-sectio...
