In vitro activity of the new oxazolidinone AZD2563 against Enterococci.
The activity of a new oxazolidinone antimicrobial, AZD2563, was assessed against >500 clinical isolates of enterococci representing six species. All isolates, including those resistant to other antibiotic classes, were inhibited by AZD2563 at concentrations </=2 micro g/ml, except for four strains resistant to linezolid. In most cases, AZD2563 was twofold more active than linezolid against ente...
متن کاملIn vitro activities in new oxazolidinone antimicrobial agents against enterococci.
The comparative in vitro activities of two new oxazolidinone antimicrobial agents, U-100592 and U-100766, against 180 isolates of enterococci representing several resistance profiles were examined by using an agar dilution technique. The two oxazolidinones inhibited all isolates, including strains resistant to vancomycin, ampicillin, and minocycline, at concentrations between 1 and 4 micrograms...
متن کاملIn vitro activity of a novel oxazolidinone, AZD2563, against randomly selected and multiresistant Gram-positive cocci.
The in vitro activity of AZD2563, a novel oxazolidinone, was assessed against 595 Gram-positive cocci, comprising recent surveillance isolates and a collection of resistant (including multiresistant), epidemiologically diverse isolates. The MICs of AZD2563 for staphylococci, pneumococci and enterococci had narrow ranges, 0.25-2 mg/L, with modal MICs of 1 mg/L for staphylococci and pneumococci, ...
متن کاملIn vitro activity of the oxazolidinone RWJ-416457 against linezolid-resistant and -susceptible staphylococci and enterococci.
RWJ-416457, a novel oxazolidinone, had modal MICs of 0.5 to 1 microg/ml for linezolid-susceptible staphylococci and enterococci, versus linezolid MICs for these organisms of 1 or 2 microg/ml. RWJ-416457 MICs for mutants with 23S rRNA mutations were 2 to 32 microg/ml, versus linezolid MICs of 8 to 64 microg/ml; actual values reflected the proportion of gene copies mutated.
متن کاملIn vitro evaluation of AZD2563, a novel oxazolidinone, against 603 recent staphylococcal isolates.
AZD2563, a novel oxazolidinone, and a selection of comparator drugs that included linezolid, erythromycin, clindamycin, quinolones, and gentamicin were tested against 384 Staphylococcus aureus (176 oxacillin-resistant S. aureus [ORSA]) and 219 coagulase-negative staphylococci (CoNS; 162 oxacillin resistant) by reference microdilution (all strains) and agar dilution (30 strains) methods. The fol...
