A rapid 24-hour protocol effectively identifies patients with vancomycin-resistant Enterococcus faecium (VRE) using molecular methods. This new screening approach demonstrates high accuracy, improving patient care and infection control.

Area of Science:

  • Clinical Microbiology
  • Infectious Diseases
  • Molecular Diagnostics

Background:

  • Vancomycin-resistant Enterococcus faecium (VRE) poses a significant healthcare-associated infection risk.
  • Rapid identification of VRE is crucial for effective infection control measures.

Purpose of the Study:

  • To develop and validate a rapid 24-hour protocol for VRE detection.
  • To assess the diagnostic performance of the new protocol compared to conventional methods.

Main Methods:

  • Utilized stool and rectal swab samples.
  • Employed VRE screening broth, automated DNA extraction, and real-time PCR targeting vanA and vanB genes.

Main Results:

  • Achieved identification of VRE-positive patients within 24 hours.
