Lecture Notes: Introduction to BiomeFX and Functional Microbiome Analysis
Introduction
- Presenter: Angelica from Microbiome Labs
- Series: Clinical science series focused on microbiome and digestive tract
- Speaker: Kara Seidman, a registered dietitian with extensive experience in microbiome-focused nutrition practices
- Event: Part of a four-part series on functional microbiome analysis
Key Topics
Importance of Microbiome
- Microbiome as the foundation of health
- Healthy microbiome contributes to a functional intestinal barrier, low inflammatory load, and resistance to chronic diseases
- Disruptors include medications, diet, stress, environmental toxins, etc.
BiomeFX Overview
- BiomeFX: Patented microbiome stool test by Microbiome Labs
- Purpose: Provides insights into gut microbial ecosystem, understanding who is in the gut, and what they are doing
- Focuses on functional capabilities of microbiome for personalized medicine and interventions
Functional Microbiome Analysis
- Uses whole genome sequencing instead of traditional 16S rRNA sequencing
- Identifies not only who is there but also the functional roles of microbes
- Allows for understanding microbial interaction and impact on health
Differences Between Traditional and Functional Stool Tests
- Traditional tests often aim for diagnosis, focusing on elimination of pathogens
- Functional tests focus on microbial diversity, ecosystem resilience, and potential health implications beyond the gut
Components of BiomeFX Test
- Diversity Measures: Alpha (richness and abundance) and Beta (quality and representation) diversity
- Resistome: Microbial genes conferring antibiotic resistance, indicating microbiome resilience
- Pathobiome: Identifies potential pathogenic species
- Dysbiosis Ratios: Imbalance in predominant phyla (Bacteroidetes, Firmicutes, etc.) can indicate metabolic or inflammatory issues
Key Species & Functions
- Keystone Species: Influence overall health despite low abundance (e.g., Akkermansia, Bifidobacterium)
- Functional Analysis: Measures production of short-chain fatty acids, ammonia, hydrogen sulfide, histamine, etc.
Potential Clinical Insights
- Helps understand dysbiosis risk factors and their impact on overall health
- Provides guidance on dietary and lifestyle modifications
- Assists in balancing the microbiome ecosystem, potentially preventing conditions before symptoms arise
Applications & Use Cases
- Applicable to both symptomatic and asymptomatic individuals
- Valuable for conditions beyond the GI tract, including metabolic, autoimmune, and liver health
Conclusion
- BiomeFX offers a comprehensive view of the gut microbiome and its functional roles
- Encourages a shift from pathogen elimination to ecosystem support and resilience building
- Part of an ongoing series to deepen understanding of microbiome impacts and interventions
Additional Resources
- Webinar series and educational resources provided by Microbiome Labs
- Includes interpretation guides, clinical consults, and support for further learning and application
These notes provide an overview of the key points covered in the presentation on BiomeFX and its role in understanding and leveraging microbiome insights for better health outcomes.
