Insights

This study investigated antibiotic resistance in enterococci, finding a 11.4% prevalence of high-level aminoglycoside-resistant (HLAR) strains. Vancomycin-resistant enterococci were not detected in the analyzed specimens.

Area of Science:

  • Microbiology
  • Infectious Diseases
  • Antimicrobial Resistance

Background:

  • Enterococci are significant nosocomial pathogens.
  • Antimicrobial resistance in enterococci, particularly high-level aminoglycoside resistance (HLAR) and vancomycin resistance, poses a major public health threat.
  • Monitoring resistance patterns is crucial for effective treatment strategies.

Purpose of the Study:

  • To determine the prevalence of HLAR and vancomycin-resistant enterococci in clinical specimens.
  • To assess the current antimicrobial resistance landscape of enterococci.

Main Methods:

  • Enterococci were isolated from 264 clinical specimens.
  • Isolation rates and resistance profiles were determined.
  • Phenotypic methods were used to identify HLAR and vancomycin resistance.

Main Results:

  • Enterococci were isolated from 70.9% of specimens.
  • Thirty strains (11.4%) exhibited high-level aminoglycoside resistance (HLAR).
  • No vancomycin-resistant enterococci were detected.

Conclusions:

  • HLAR enterococci are prevalent in the studied population.
  • The absence of vancomycin-resistant enterococci suggests current control measures may be effective, but continued surveillance is warranted.
  • These findings highlight the importance of monitoring specific resistance mechanisms in enterococcal infections.
