Enterococci are bacteria that live in the intestines of most individuals and generally do not cause harm. Vancomycin-resistant Enterococci (VRE) are strains of enterococci that are resistant to the antibiotic vancomycin. If a person has an infection caused by Vancomycin-resistant Enterococci (VRE) it may be more difficult to treat.
Vancomycin-resistant Enterococci (VRE) is defined as a patient identified with laboratory-confirmed bloodstream infection with Vancomycin-resistant Enterococci.
