Accessory Gene Regulator (agr) Locus in Geographically Diverse Staphylococcus aureus Isolates with Reduced Susceptibility to Vancomycin
ABSTRACT The majority of infections with glycopeptide intermediate-level resistant Staphylococcus aureus (GISA) originate in biomedical devices, suggesting a possible increased ability of theseExpand

Linezolid resistance in sequential Staphylococcus aureus isolates associated with a T2500A mutation in the 23S rRNA gene and loss of a single copy of rRNA.
Linezolid is an important therapeutic option for infections caused by resistant gram-positive bacteria. We report the characterization of sequential methicillin-resistant Staphylococcus aureus (MRSA)Expand

Linezolid resistance in Staphylococcus aureus: characterization and stability of resistant phenotype.
Linezolid is an important therapeutic option for treatment of infections caused by glycopeptide- and beta-lactam-resistant gram-positive organisms. Linezolid resistance is caused by mutations withinExpand

Development of reduced vancomycin susceptibility in methicillin-susceptible Staphylococcus aureus.
BACKGROUND Most cases of reduced vancomycin susceptibility in Staphylococcus aureus reported in the literature have been in methicillin-resistant strains. We report the development of reducedExpand

Antibiotic Synergism Against Listeria monocytogenes1
The effectiveness of ampicillin, penicillin, streptomycin, and gentamicin against 20 strains of Listeria monocytogenes was studied in vitro. For all strains, the minimal bactericidal concentrationExpand

High-level resistance to gentamicin in clinical isolates of Streptococcus (Enterococcus) faecium.
During a 14-month period beginning in July 1986, three distinct clinical isolates of Streptococcus (Enterococcus) faecium demonstrating high-level resistance (MIC, greater than 2,000 micrograms/ml)Expand

Staphylococcus aureus accessory gene regulator (agr) group II: is there a relationship to the development of intermediate-level glycopeptide resistance?
We previously determined that all 6 Staphylococcus aureus strains with confirmed intermediate-level resistance to glycopeptides (glycopeptide intermediate S. aureus [GISA]) from the United StatesExpand

Emergence of a Clinical Daptomycin-Resistant Staphylococcus aureus Isolate during Treatment of Methicillin-Resistant Staphylococcus aureus Bacteremia and Osteomyelitis
ABSTRACT The emergence of a clinically daptomycin-resistant Staphylococcus aureus isolate occurred during treatment of methicillin-resistant S. aureus bacteremia and probable vertebral osteomyelitis.Expand

Antimicrobial Susceptibility of Flavobacteria
Antimicrobial susceptibility patterns of 28 clinical isolates of Flavobacterium sp. were determined by standard disk diffusion technique and by antimicrobial dilution in agar. Rifampin, clindamycin,Expand

Continuous-infusion ampicillin therapy of enterococcal endocarditis in rats.
Intermittent administration of ampicillin alone has resulted in high failure rates in previously described animal models of enterococcal endocarditis. We developed a rat model of enterococcalExpand
