Enterococcus faecalis: implications for host health

Area of Science:

• Microbiology
• Human Health Research
• Gut Microbiome Studies

Background:

• The human microbiota is vital for health, offering biomarkers and therapies.
• Enterococcus faecalis, a gut bacterium, presents a dual nature: beneficial probiotic or pathogenic agent.
• Its antibiotic resistance raises concerns for severe infections.

Purpose of the Study:

• To comprehensively review the impact of Enterococcus faecalis strains on host systems.
• To summarize bacterium-host interactions and molecular effects.
• To highlight targets, features, and overall impact on microbial communities and host health.

Main Methods:

• Literature review of Enterococcus faecalis research.
• Analysis of studies on host system interactions (immunological, cardiovascular, metabolic, nervous).
• Synthesis of data on bacterium-host interactions and molecular mechanisms.

Main Results:

• Enterococcus faecalis strains exhibit diverse characteristics, influencing multiple host systems.
• The bacterium's interactions are complex, with significant molecular effects.
• Understanding these interactions is key to characterizing its role in health and disease.

Conclusions:

• Enterococcus faecalis has a significant, multifaceted impact on host health.
• Further research into its interactions can reveal novel therapeutic targets.
• Characterizing strain-specific properties is crucial for managing its dual role.
