Leprosy Diagnostic Landscape

Nanopore Targeted and Whole-Genome Sequencing

Long-read sequencing of enriched or high-burden specimens for genotyping, single-nucleotide-polymorphism typing and reconstruction of transmission chains. Direct sequencing is constrained by the low proportion of bacillary DNA in clinical material.

Technology
Molecular (NAAT) · Next-generation sequencing
What it measures
M. leprae genome, for strain typing and resistance
Developer
Oxford Nanopore-based laboratory workflows
Specimen
Skin biopsy
Development status
RUO with analytical validation
Regulatory status
None / RUO
Intended use
Strain typing and reconstruction of transmission chains
Main limitation
Clinical samples contain little bacterial DNA, so enrichment is needed.
Linked publications
TPP-1, confirming leprosy
30.0 of 100, low alignment
