CRISPR elements and their association with antimicrobial resistance and virulence genes among vancomycin-resistant and vancomycin-susceptible enterococci recovered from human and food sources.

We aimed to investigate the occurrence of CRISPR elements in the genomes of vancomycin-resistant (VRE) and vancomycin-susceptible (VSE) enterococci and their association with the presence of antimicrobial resistance and virulence genes. We analyzed 180 isolates, including 91 VRE and 89 VSE. Isolates were identified by PCR or MALDI-TOF.
