Vancomycin intermediate Staphylococcus aureus (VISA) and Vancomycin resistant Staphylococcus aureus (VRSA)

What is Staphylococcus aureus?

Staphylococcus aureus is a bacteria that is found on the skin (armpit, groin, and genital areas) and in the nose of many people and normally does not cause illness. When these germs enter the body through a break in the skin, they can cause infections such as, pimples and boils, or serious infections such as, bloodstream infections, pneumonia, or surgical site infections. For many years Staphylococcal infections have been treated with antibiotics and now the bacteria have become resistant to some antibiotics.

What are VISA and VRSA?

VISA and VRSA are a type of Staphylococcus aureus that have developed resistance to the antibiotic Vancomycin; therefore, cannot be treated with Vancomycin. While VISA and VRSA infections are rare, they are serious and difficult to treat.
