Limitations of 16S rRNA Sequencing
MOST MICROBIOME TESTING METHODS TODAY ARE PROBLEMATIC
The microbiome testing industry has largely relied on 16S rRNA sequencing as the standard method for identifying microbial communities.
While this approach has provided valuable insights, it is significantly limited:
- Limited Taxonomic Resolution: 16S sequencing typically only identifies bacteria to the genus level, not species or strain level, missing critical functional differences between closely related microbes.
- Missing Microbial Diversity: This approach fails to detect viruses, fungi, bacteriophages, and even some bacteria that play crucial roles in microbiome health and disease states.
- No Functional Insights: 16S sequencing identifies "who is there" but doesn’t provide information about “what they do”: microbial functions, metabolic pathways, or virulence factors.
- Semi-Quantitative at Best: Traditional 16S methods provide relative abundance rather than absolute quantification, making it impossible to determine if a pathogen is present at clinically relevant levels.
- Biased Amplification: PCR amplification in 16S sequencing introduces biases, over-representing some bacterial groups while under-representing others, which is made worse by variable 16S rRNA copy numbers between species
Shortcomings of Non-Quantitative Whole Genome Sequencing
While standard whole genome sequencing (WGS) addresses some 16S limitations, non-quantitative approaches still face significant challenges:
- Lack of Absolute Quantification: Without proper quantification methods, WGS still provides only relative abundance data, limiting clinical utility.
- Variable Genome Coverage: Standard WGS often results in uneven coverage across different microbes, particularly those with extreme GC content.
- Incomplete Pathogen Identification: Without quantitative benchmarks, determining whether detected organisms represent active infections or harmless colonization remains problematic.
- Analytical Challenges: Non-quantitative WGS generates massive datasets without the standardization necessary for comparing results between samples.
- Insufficient Depth: Cost constraints often limit sequencing depth, missing low-abundance but clinically significant pathogens.
