Question

Quizplus · Accepted Answer

Vancomycin-intermediate Staphylococcus aureus (VISA) is a type of MRSA that displays decreased susceptibility to vancomycin. This means that the person is no longer responding to vancomycin therapy, indicating that they may have VISA. VRE (vancomycin-resistant enterococcus) refers to a different type of bacteria that is resistant to vancomycin, but it is not MRSA. MDR-TB (multi-drug resistant tuberculosis) and ESBL (extended-spectrum beta-lactamase) are also types of antibiotic-resistant bacteria, but they are not related to MRSA or vancomycin.
