Vancomycin-resistant enterococci (VRE) are a type of bacteria that have developed resistance to the antibiotic vancomycin, which is often used to treat serious infections. These bacteria are commonly found in the intestines and can spread to other parts of the body, leading to infections that are difficult to treat. VRE infections can occur in patients with weakened immune systems, particularly in healthcare settings like hospitals. They can cause various health issues, including urinary tract infections and bloodstream infections. Preventing the spread of VRE involves good hygiene practices, such as handwashing and proper cleaning of medical equipment.
