What defines Vancomycin-Resistant Enterococcus (VRE)?

Vancomycin-Resistant Enterococcus (VRE) is indeed defined as a gram-positive bacterium that resides primarily in the gastrointestinal tract. This organism is part of the normal flora in many healthy individuals, yet it can become an issue when it causes infections, particularly in healthcare settings among patients with weakened immune systems.

The characteristic of resistance refers specifically to the bacterium’s ability to withstand treatment with vancomycin, an antibiotic that is typically effective against many strains of enterococci. The emergence of VRE is linked to the use of antibiotics, which can disrupt normal flora and create opportunities for these resistant strains to proliferate.

Understanding the nature and risks associated with VRE is crucial in infection prevention practices, particularly in nursing homes where vulnerable populations are present. This awareness helps in implementing appropriate infection control measures to prevent the spread of this pathogen.
