The Role of Probiotics and Prebiotics in Decolonizing Pathogenic Bacteria: Evidence-Based Insights

Interesting News . Dec 27, 2024

Introduction

The widespread use of antibiotics and environmental shifts have significantly impacted gut microbial diversity, increasing susceptibility to infections by drug-resistant pathogens. As antimicrobial resistance (AMR) continues to pose a public health challenge, recent studies highlight probiotics and prebiotics as potential interventions to restore gut microbiota and reduce pathogen colonization.

A 2024 systematic review and meta-analysis published in Gut Microbes by Rahman and co-authors assessed the efficacy of probiotics and prebiotics in decolonizing AMR pathogens in human and animal studies. Here’s a summary of the findings and their implications for product development in the nutraceutical and functional food sectors.

Key Findings from the Meta-Analysis

Individuals with severe health conditions such as acute pancreatitis, inflammatory bowel disease, liver disease, or HIV are advised to consult healthcare professionals before probiotic supplementation.

  1. Probiotic Efficacy
    • Decolonization Rates:
      • Persistence of pathogenic bacteria was significantly lower in the probiotic group (22%) compared to placebo (30.8%).
      • The pooled odds ratio for decolonization favored probiotics (OR: 0.59; 95% CI: 0.43–0.81; p = 0.0001) with moderate certainty.
    • Pathogen-Specific Results:
      • Clostridioides difficile (C. difficile): Highest decolonization rate at 82.4%.
      • Lactobacillus-based Probiotics: Decolonized 71% of pathogens.
      • Saccharomyces boulardii: Achieved 77% decolonization.
    • Subgroup Analysis:
      • Types of probiotics and pathogens significantly moderated outcomes (p < 0.02).
      • Dosage and geographic regions showed no significant impact (p > 0.05).
  2. Prebiotic Effectiveness
    • Prebiotics reduced pathogen load by 30% to 80% through modulation of gut microbial diversity.
    • Evidence suggests prebiotics enhance the colonization resistance of the gut microbiome.
  3. Evidence Strength and Limitations
    • The analysis reported moderate certainty for probiotics and prebiotics in decolonizing pathogens.
    • Further clinical studies focusing on specific strains are needed to validate these findings.
