Summary
This study on Enterococcus faecium found high resistance to aminoglycosides and low resistance to vancomycin (99.46% susceptible). Six vancomycin-resistant isolates were identified, highlighting the need for control.
Area of Science:
- Microbiology
- Infectious Diseases
- Clinical Research
Context:
- Antibiotic resistance in Enterococcus faecium is a growing global health concern.
- E. faecium is a common cause of hospital-acquired infections.
- Monitoring resistance patterns is crucial for effective treatment strategies.
Purpose:
- To investigate the antibiotic susceptibility and resistance patterns of Enterococcus faecium isolates.
- To compare resistance profiles between intrahospitalary and extrahospitalary strains.
- To assess the prevalence of vancomycin resistance in E. faecium.
Summary:
- A total of 637 E. faecium isolates from urine, blood, and wound swabs (2004-2010) were analyzed using the WIDER I system.
- High susceptibility rates were observed for linezolid (100%) and vancomycin (99.46%).
- Significant resistance to aminoglycosides (41.41-73.55%) was noted, along with six vancomycin-resistant isolates (five intrahospitalary, one extrahospitalary).
Impact:
- Findings highlight the critical need for vigilant monitoring and control of vancomycin resistance in E. faecium.
- The study provides valuable data for guiding empirical antibiotic therapy and infection control measures.
- Understanding local resistance trends is essential for optimizing patient outcomes and preventing treatment failures.

Clinical Significance of Antibiotic Resistance
Methicillin-resistant Staphylococcus aureus (MRSA) presents a critical public health threat, arising from its capacity to resist β-lactam antibiotics due to acquisition of the mecA gene within the staphylococcal cassette chromosome mec (SCCmec). This gene encodes penicillin-binding protein 2a (PBP2a), which impairs binding efficacy of methicillin and other β-lactams. MRSA has evolved into distinct clonal lineages impacting humans and animals alike, reinforcing its significance within the One...
Antimicrobial Effectiveness
The effectiveness of antimicrobial agents depends on various factors influencing their ability to eliminate microbial populations. Larger microbial populations require more time for complete eradication, emphasizing the importance of population size analysis when evaluating antimicrobial efficacy.Microbial resistance to antimicrobial agents varies significantly. Highly resilient microorganisms include endospores, gram-negative bacteria, and non-enveloped viruses, while prions are exceptionally...
Mechanism of Antibiotic Resistance in MRSA
Antibiotic resistance in bacteria arises when microorganisms evolve the ability to withstand drugs designed to kill them or inhibit their growth, rendering once-effective treatments useless. This phenomenon, driven by genetic change and selection under antibiotic exposure, poses a profound threat to modern medicine. Mechanisms include drug-inactivating enzymes (e.g., β-lactamases), efflux pumps that eject antibiotics, mutations altering antibiotic targets, decreased drug uptake, and acquisition...
Development of Antibiotic Resistance
Antibiotic resistance is a major public health concern that arises when bacteria evolve mechanisms to withstand the effects of antibiotic treatments. This resistance can be intrinsic, acquired through genetic mutations, or transferred between bacteria via horizontal gene transfer. The development of antibiotic resistance poses significant challenges in treating bacterial infections and necessitates ongoing research to develop new therapeutic strategies.Intrinsic resistance occurs when bacterial...
