Molecular epidemiology and clinical characteristics of hetero-resistant vancomycin intermediate Staphylococcus aureusbacteremia in a Taiwan Medical Center

Hetero-resistant vancomycin intermediate Staphylococcus aureus(hVISA) emerges worldwide in recent decade. The purpose of this study was to investigate the glycopeptide usage trend, the prevalence of methicillin-resistant Staphylococcus aureus(MRSA) with reduced vancomycin susceptibility, the susceptible rates to newer antimicrobials, molecular epidemiology, clinical characteristics, as well as patient outcome among S. aureusbacteremia cases in a Taiwanese medical center.
