What does VRSA stand for?

• A. Vancomycin-resistant Staphylococcus aureus
• B. Vancomycin-resistant Streptococcus aureus
• C. Vancomycin-resistant Staphylococcus aureus bacteremia
• D. Vancomycin-sensitive Staphylococcus aureus

Answer: (A)

VRSA indicates a bacterium that is resistant to vancomycin, specifically Staphylococcus aureus. Vancomycin is a key antibiotic used to treat serious infections caused by Gram-positive bacteria, so when Staphylococcus aureus becomes resistant to it, we label the strain VRSA to signal treatment challenges and infection-control concerns. The term refers to the organism and its resistance, not to a particular infection site or a different genus. For example, a name that uses Streptococcus aureus would be incorrect because Streptococcus and Staphylococcus are distinct genera. Adding “bacteremia” would describe a bloodstream infection, not the resistance status of the organism itself. And saying vancomycin-sensitive would mean the bacterium can still be treated with vancomycin, which contradicts the idea of resistance.
