Enterococcus faecium: evolution, adaptation, pathogenesis and emerging therapeutics

Area of Science:

• Microbiology
• Infectious Diseases
• Evolutionary Biology

Background:

• Enterococcus faecium is an opportunistic pathogen found in humans and animals.
• It exhibits high stress tolerance and antibiotic resistance, contributing to hospital-acquired infections.
• The emergence of vancomycin-resistant Enterococcus faecium (VRE) is a significant clinical concern.

Purpose of the Study:

• To review recent discoveries on the evolutionary history of E. faecium.
• To explore environmental adaptation, colonization, and dissemination mechanisms of E. faecium and VRE.
• To provide insights for developing novel strategies against VRE.

Main Methods:

• This is a review article, synthesizing existing research.
• It analyzes studies on the evolutionary trajectory of E. faecium.
• It examines research on microbial adaptation and pathogen spread.

Main Results:

• E. faecium possesses remarkable resilience and adaptability.
• Antibiotic overuse has driven the rise of VRE.
• Complex interactions between environment, host, and microorganism facilitate pathogen endurance.

Conclusions:

• Understanding E. faecium's biology is crucial for infection control.
• Novel preventive and therapeutic approaches against VRE are needed.
• Insights into pathogen emergence and persistence have broad implications for public health.
