Vancomycin (VAN) Combinations with Β-Lactams (BLs) against Methicillin-Resistant Staphylococcus aureus (MRSA), Heterogeneous Intermediate-Level Resistance to Vancomycin (hVISA) and Vancomycin-Intermediate Staphylococcus aureus (VISA)

Vancomycin (VAN) Combinations with Β-Lactams (BLs) against Methicillin-Resistant Staphylococcus aureus (MRSA), Heterogeneous Intermediate-Level Resistance to Vancomycin (hVISA) and Vancomycin-Intermediate Staphylococcus aureus (VISA)

Detection of heterogeneous, intermediate-vancomycin-resistant Staphylococcus aureus (hVISA) using low-concentration vancomycin disks.

Heterogeneous, intermediate-vancomycin-resistant Staphylococcus aureus (hVISA) represents a threat of an incurable infection since the first report in 1997. The method used to detect hVISA isolates is a population analysis profile (PAP); however, it is impractical for routine laboratory analysis. We therefore tested a simple, reliable and inexpensive method for the detection of hVISA. Eighteen ...

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...

Daptomycin non-susceptibility in vancomycin-intermediate Staphylococcus aureus (VISA) and heterogeneous-VISA (hVISA): implications for therapy after vancomycin treatment failure.

OBJECTIVES The aim of this study was to establish the relationship between reduced vancomycin and daptomycin susceptibility among Australasian vancomycin-intermediate Staphylococcus aureus (VISA) and heterogeneous-VISA (hVISA) isolates from patients never exposed to daptomycin. METHODS Forty-seven stored clinical isolates of hVISA/VISA collected before November 2008 from around Australia and ...

Methicillin-Resistant Staphylococcus aureus (MRSA), Vancomycin-Resistant Staphylococcus aureus (VRSA), and Vancomycin-Resistant Enterococci‌ (VRE) contamination of food samples in Iran: A systematic review and meta-analysis

During the last years, antimicrobial resistance has become one of the greatest challenges in clinical settings. Staphylococcus aureus and Enterococcus are important nosocomial pathogens worldwide. In different corners of the world, methicillin-resistant Staphylococcus aureus (MRSA) and vancomycin-resistant enterococci (VRE) have been isolated from various sources including different foods of an...
