the Vancomycin Intermediate Staphylococcus aureus (VISA)

Vancomycin Intermediate Staphylococcus aureus (VISA) is a type of bacteria that causes infections and has developed a reduced sensitivity to the antibiotic vancomycin, which is often used to treat serious staph infections. Unlike fully resistant bacteria, VISA is only partially resistant, meaning vancomycin may not be as effective in clearing the infection. This resistance results from changes in the bacteria’s cell wall that make it harder for the antibiotic to work properly. VISA infections are more difficult to treat and require careful management to prevent treatment failure and the spread of resistant strains.
