Listeria and WGS

Listeria Monocytogenes (LG) and Whole Genome Sequencing (WGS) Name Institution Course Instructor Date Listeria Monocytogenes (LG) and Whole Genome Sequencing (WGS) Listeria monocytogenes (LG) is a far-reaching foodborne pathogen that causes severe illness. Detecting and subtyping LG in a precise manner prevents and controls outbreaks, benefiting food safety management. Powerful tools such as whole genome sequencing (WGS) help identify and track Listeria more precisely. The most straightforward aspect of WGS for Listeria detection and subtyping is its superior discriminatory power compared to traditional methods such as pulsed-field gel electrophoresis (PFGE). According to Parra-Flores et al. (2025), sequencing presents high-resolution, complete genomic information, allowing researchers to differentiate highly related strains that appear identical using regular methods. This WGS characteristic enables identif...
