Expression and detection of hetero-vancomycin resistance in Staphylococcus aureus

Vancomycin Resistance in Staphylococcus aureus Strains

Prevalence of Vancomycin Resistance in Methicillin-Resistant Staphylococcus Aureus

Background & Aims: Staphylococcus aureus is one of the most common pathogens in nosocomial infections. Vancomycin is the most important therapeutic drug of choice for treatment of infections caused by methicillin-resistant Staphylococcus aureus (MRSA) strains. Therefore, vancomycin-resistant Staphylococcus aureus (VRSA) or vancomycin-intermediate Staphylococcus aureus (VISA) strains are warning...

Vancomycin Resistance in Staphylococcus aureus


The evolution of Staphylococcus aureus during the modern antibiotic era has been delineated by distinct strain emergence events, many of which include acquisition of antibiotic resistance. The relative high burden of methicillin-resistant S. aureus (MRSA) in healthcare and community settings is a major concern worldwide. Vancomycin, a glycopeptide antibiotic that inhibits cell wall biosynthesis...

Vancomycin resistance in Staphylococcus aureus.

Vancomycin resistance in enterococci, predominantly Enterococcus faecium, developed in the latter half of the 1980s, and the long anticipated development of vancomycin resistance in Staphylococcus aureus has now occurred. A number of vancomycin-intermediate strains have been described, and these strains have abnormal, thickened cell walls in the presence of vancomycin. Two mechanisms of resista...

Vancomycin Resistance Pattern of Staphylococcus Aureus among Clinical Samples

Abstract Background and Objective: Vancomycin is used for treatment of methicillin-resistant S. Aureus (MRSA) infections therefore, resistance to this antibiotic is increasing. We aimed to determine the antibiotic resistance pattern and frequency of vancomycin resistant S. Areas (VRSA) strains isolated from clinical samples. Material and Methods: In this cross-sectional study, 100 S. Aureus iso...
