Clinical WGS Pipelines
One-Sentence Definition
Clinical WGS pipelines are validated, version-controlled workflows that turn bacterial sequencing reads into QC-gated reports for identification, typing, AMR/virulence genes, and relatedness suitable for patient care or public health.
Simple Explanation
A locked recipe — not an ad-hoc laptop script — that hospitals and reference labs use so genome results are repeatable, documented, and clinically safe.
Detailed Scientific Explanation
Representative frameworks:
| Framework | Notes |
|---|---|
| Bactopia | Batteries-included bacterial WGS toolkit |
| nf-core/bacass & friends | Nextflow community pipelines |
| TheiaProk / CDC PulseNet tools | Public-health oriented stacks |
| Custom ISO-accredited pipelines | Lab-specific validation |
Typical stages mirror WGS Bioinformatics Pipeline but add: SOPs, reference databases with pinned versions, audit logs, Assembly Quality Control gates, and human-readable clinical interpretation limits.
Validation needs analytical sensitivity/specificity for AMR genes and reproducibility across techs/instruments (Reproducible Bioinformatics Workflows, Model Evaluation in Clinical Microbiology).
Mechanism
Raw reads → automated workflow manager → QC gates → typed outputs → signed clinical/epi report with database versions.
Clinical Importance
- Converts research-grade genomics into actionable stewardship and infection-control decisions.
- Defines what must not be reported (low confidence calls).
Research Importance
- Bridges FAIR surveillance datasets (FAIR Data and Genomic Surveillance).
Diagnostic Relevance
This is the diagnostic productization layer of bacterial genomics.
AMR Relevance
Report genotype with phenotype caveats; genotype ≠ automatic therapy change without rules (Genotype to Phenotype Prediction).
