Vancomycin-resistant enterococci in healthcare settings: clonal analysis, resistance profiles, and biofilm formation of strains isolated from hospitalized patients

Puntos clave

• Vancomycin-resistant enterococci exhibit varied resistance profiles, impacting treatment options.
• In hospitalized patients, 75% of the isolated strains formed biofilms, increasing infection risks.
• Clonal analysis identifies distinct clusters among enterococci, highlighting transmission patterns in healthcare.
• Infection prevention must address biofilm formation, as these factors complicate treatment efficacy.
