Methicillin and Vancomycin Resistant S. aureus in Hospitalized …
It has been suggested that patients at risk for VRSA are co-infected or co-colonized with VRE and MRSA, which enables transfer of vanA gene from VRE to MRSA in a biofilm environment leading to a VRSA strain.
Vancomycin Resistance in Staphylococcus aureus - PMC
S. aureus isolates with complete resistance to vancomycin (MIC ≥ 16 µg/mL) are termed vancomycin-resistant S. aureus (VRSA)—they were first reported in the U.S. in 2002. Resistance in VRSA is conferred by the vanA gene and operon, which is present on a plasmid.

2024年4月15日 · Clinical laboratories should save all Vancomycin-resistant Enterococci (VRE), Methicillin-resistant Staphylococcus aureus (MRSA) and VRSA isolates from patients with suspected or confirmed VRSA and share confirmed isolates with public health partners.
Methicillin-resistant Staphylococcus aureus - Wikipedia
Methicillin-resistant Staphylococcus aureus (MRSA) is a group of gram-positive bacteria that are genetically distinct from other strains of Staphylococcus aureus. MRSA is responsible for several difficult-to-treat infections in humans. It caused more than 100,000 deaths worldwide attributable to antimicrobial resistance in 2019.
MRSA: Causes, Symptoms, Diagnosis, Treatment & Prevention
2024年5月7日 · MRSA (methicillin-resistant Staphylococcus aureus) is a type of bacteria that many antibiotics don’t work on. MRSA most often causes skin infections, but it can also cause serious illnesses that are hard to treat. MRSA skin infections might look like a rash or an area that’s red, discolored, painful, swollen, or filled with pus or fluid.

Vancomycin Resistance in Staphylococcus aureus - PubMed
2017年6月23日 · S. aureus isolates with complete resistance to vancomycin (MIC ≥ 16 µg/mL) are termed vancomycin-resistant S. aureus (VRSA)-they were first reported in the U.S. in 2002. Resistance in VRSA is conferred by the vanA gene and operon, which is present on a plasmid.
Mechanisms of vancomycin resistance in Staphylococcus aureus
This greatly increased selective pressure resulted in the emergence of MRSA isolates with reduced susceptibility to vancomycin — the so-called VISA strains — and, most recently, to the appearance of VRSA strains with high-level resistance to the antibiotic.
Vancomycin Intermediate Staphylococcus aureus (VISA) and …
VISA and VRSA are classified as “intermediate” or “resistant” based on lab tests. Similar to MRSA, it is spread through contact. VISA/VRSA infections are rare.
