Antimicrobial Susceptibility Patterns and Macrolide Resistance Genes of β-Hemolytic Viridans Group Streptococci in a Tertiary Korean Hospital
The aim of this study was to investigate antimicrobial susceptibilities and macrolide resistance mechanisms of beta-hemolytic viridans group streptococci (VGS) in a tertiary Korean hospital. Minimum inhibitory concentrations (MICs) of seven antimicrobials were determined for 103 beta-hemolytic VGS isolated from various specimens. The macrolide resistance mechanisms of erythromycin-resistant iso...
متن کاملAntimicrobial Susceptibility Patterns and Macrolide Resistance Genes of -Hemolytic Streptococci in Korea
In 540 beta-hemolytic streptococci, the rates of resistance to tetracycline, chloramphenicol, erythromycin, and clindamycin were 80.0, 22.8, 20.2, and 19.1%, respectively. Of the erythromycin-resistant isolates, 63.3% had the constitutive macrolide-lincosamide-streptogramin B (MLSB) resistance phenotype, 23.9% had the M phenotype, and 12.8% had the inducible MLSB resistance phenotype. The const...

متن کاملEvaluation of the MicroScan MICroSTREP Plus Antimicrobial Panel for Testing β-Hemolytic Streptococci and Viridans Group Streptococci
BACKGROUND In order to determine the clinical usefulness of the MicroScan (Siemens Healthcare Diagnostics, USA) MICroSTREP plus antimicrobial panel (MICroSTREP) for testing antimicrobial susceptibility of β-hemolytic streptococci (BHS) and viridans group streptococci (VGS), we compared the accuracy of MICroSTREP with that of the CLSI reference method. METHODS Seventy-five BHS and 59 VGS isola...
متن کاملMacrolide Resistance Trends in β-Hemolytic Streptococci in a Tertiary Korean Hospital
PURPOSE Erythromycin-resistant beta-hemolytic streptococci (BHS) has recently emerged and quickly spread between and within countries throughout the world. In this study, we evaluate the antimicrobial susceptibility patterns and erythromycin resistance mechanisms of BHS during 2003-2004. MATERIALS AND METHODS The MICs of seven antimicrobials were determined for 204 clinical isolates of BHS fr...
