Enterococcal Phages: Food and Health Applications

Area of Science:

• Microbiology
• Food Science
• Infectious Diseases

Background:

• Enterococcus is a Gram-positive lactic acid bacteria (LAB) genus found in the human gut and fermented foods.
• Enterococcus species like Enterococcus faecium and Enterococcus faecalis have dual roles: beneficial in food fermentation and as emerging hospital-acquired pathogens.
• Concerns include biogenic amine production in food and increasing antimicrobial resistance (AMR) in clinical settings.

Purpose of the Study:

• To review the challenges posed by Enterococcus faecium and Enterococcus faecalis in food and healthcare.
• To highlight recent advancements in bacteriophage discovery and application against these bacteria.
• To focus on bacteriophage applications targeting AMR Enterococcus infections.

Main Methods:

• Literature review of Enterococcus research.
• Analysis of bacteriophage applications against Enterococcus.
• Focus on bacteriophages targeting AMR strains.

Main Results:

• Enterococcus species are significant in food production but also cause food safety issues and infections.
• Antimicrobial resistance in Enterococcus necessitates novel therapeutic strategies.
• Bacteriophages are effective, targeted agents for controlling Enterococcus populations, including AMR strains.

Conclusions:

• Bacteriophages represent a viable alternative to antibiotics for managing Enterococcus.
• Targeted phage therapy can address both food safety concerns and clinical infections caused by Enterococcus.
• Further research into enterococcus-infecting bacteriophages is crucial for developing new antimicrobials.
