Vancomycin Susceptibility Trends and Prevalence of Heterogeneous Vancomycin-Intermediate <i>Staphylococcus aureus</i> in Clinical Methicillin-Resistant <i>S. aureus</i> Isolates

Abstract excerpt

Due to the rise in methicillin-resistant Staphylococcus aureus (MRSA) infections and widespread use of vancomycin, MRSA isolates with reduced susceptibility to vancomycin are emerging (i.e., MIC creep). However, the prevalence of heterogeneous vancomycin-intermediate S. aureus (hVISA) is unknown due to the difficulty in detecting this phenotype. Recently, Etest glycopeptide resistance detection (GRD) strips have...
