Vancomycin-resistant enterococci

Area of Science:

• Microbiology
• Infectious Diseases
• Antimicrobial Resistance

Background:

• Vancomycin-resistant enterococci (VRE) are a growing global health concern.
• VRE infections present limited therapeutic options due to co-resistance to other antimicrobials.
• The potential for VRE to transfer resistance genes to other pathogens, like MRSA, is a major concern.

Purpose of the Study:

• To highlight the increasing prevalence and implications of VRE.
• To discuss the emergence of VRE in Singapore, including community-acquired infections.
• To emphasize the role of laboratory detection and susceptibility testing in managing VRE.

Main Methods:

• Review of case reports and epidemiological studies on VRE.
• Analysis of factors contributing to VRE emergence, including glycopeptide use in animal feed.
• Discussion of risk factors for VRE bacteremia, such as prior vancomycin use.

Main Results:

• VRE stool carriage exceeds 10% in Singapore.
• A community-acquired VRE urinary tract infection case was reported.
• Emergence of VRE in Europe is linked to avoparcin use in animal feed.
• Clonal dissemination and nosocomial transmission of VRE are evident.

Conclusions:

• VRE poses a significant challenge due to limited treatment options and potential for antimicrobial resistance gene transfer.
• There is an urgent need to assess and enhance infection control measures in Singapore to prevent VRE endemicity.
• Laboratory diagnostics are critical for VRE detection and guiding antimicrobial therapy.
