The ability of MicroScan rapid panels (Baxter MicroScan, West Sacramento, Calif.) to detect oxacillin resistance in 92 clinical isolates of Staphylococcus aureus and 103 coagulase-negative staphylococci was evaluated by comparing results with those of MicroScan 24-h MIC panels and, to resolve discrepancies, oxacillin agar screening. Both panels were interpreted by the MicroScan WalkAway-96 syst...
A total of 398 consecutive clinical staphylococcus isolates, of which 205 were coagulase negative and 193 were coagulase positive, were tested in parallel by using AutoMicrobic system Gram-Positive Susceptibility-MIC cards and modified Mueller-Hinton agar containing 4% NaCl and oxacillin (6 micrograms/ml). The AutoMicrobic system cards correctly detected 103 of 104 (99%) oxacillin-resistant coa...
OBJECTIVES Epidemiology of methicillin-resistant Staphylococcus aureus (MRSA) is poorly defined in cystic fibrosis (CF) patients, and S. aureus detection may be hampered by the presence of small colony variants (SCVs). We conducted a multicentre survey to determine the prevalence of S. aureus and MRSA colonization in Belgian CF patients and characterize the phenotype and clonal distribution of ...
BACKGROUND AND OBJECTIVES Staphylococcus aureus is one of the main causatives of bovine mastitis. Resistance of some strains to methicillin, can complicate the treatment of its infections. On the other hand, enterotoxin production is also important. Therefore, the aim of our study was to investigate the methicillin resistance and enterotoxin production in S. aureus isolates caused bovine mastit...
Eighty-four pneumococci with various MICs of penicillin (38 with MICs of less than or equal to 0.06 micrograms/ml [susceptible], 35 with MICs of 0.12 to 1.0 micrograms/ml [relatively resistant], and 11 with MICs of greater than 1.0 micrograms/ml [resistant] ) were screened by a disk diffusion test using oxacillin and methicillin to see how well they distinguished penicillin-susceptible strains ...
Aims—To evaluate the BBL® CrystalTM MRSA ID System for detection of oxacillin resistance in Staphylococcus aureus. Methods—52 methicillin resistant S aureus (MRSA) from five diVerent countries and 85 methicillin susceptible S aureus (MSSA) were included. The species was confirmed by tube coagulation and detection of the clumping factor using the Staphaurex Plus. Clonal non-identity of the MRSA ...

Staphylococcus aureus strains with resistance to methicillin or oxacillin (MRSA) represent one of the main nosocomial pathogens at present. MRSA infections are clearly associated with higher mortality and economic cost than those caused by methicillin-susceptible S. aureus (1). In Spain, the prevalence of methicillin resistance among S. aureus isolates has increased since the 1990s and in some ...
Rapid and accurate detection of Methicillin Resistant Staphylococcus aureus (MRSA) is an important role of clinical microbiology laboratories to avoid treatment failure. The detection of MRSA is based on phenotypic assays which require at least 24 h to perform. Detection of the mecA gene or of PBP 2a is the "gold standard", but not always available. The aim of this study was to evaluate a rapid...
