Detection of Fish Pathogens Using Variable Number Tandem Repeat (VNTR) Analysis

Executive Industry Relevance

Multi-locus VNTR analysis using capillary electrophoresis enables precise genetic profiling of fish-pathogenic bacteria, supporting early-stage pathogen identification and risk assessment in biopharma R&D. This workflow enhances predictive confidence in microbial source tracking and informs portfolio decisions for vaccine or therapeutic development targeting aquatic pathogens. The method's reproducibility and quantitative outputs position it as a robust tool for translational research and assay development pipelines.
