Overview

Study identifies antimicrobial resistance genes in Enterococcus faecalis, highlighting implications for epidemiological surveillance.

Key Points

  • 35.3% of Enterococcus faecalis isolates showed acquired resistance, primarily to gentamicin and streptomycin.
  • The resistance genes identified include ermB, tetM, and aac(6')-Ie-aph(2")-Ia, indicating significant antimicrobial resistance.
  • Microbiological identification and PCR methods were used to profile resistance among endodontic isolates.
  • Findings point to the oral cavity being a reservoir of antimicrobial resistance, emphasizing the need for enhanced surveillance.
