Quasi-metagenomics

Quick and accurate pathogen detection and fingerprinting is critical and potentially lifesaving in foodborne outbreak responses. Currently, detecting and fingerprinting foodborne pathogens are separate processes that can take days or weeks to finish. A study at the UGA Center for Food Safety demonstrated substantial acceleration of the respective process through IMS-MDA and real-time nanopore sequencing. They developed a system that combines detection and strain-level identification of Salmonella from food samples in a fraction of time taken by traditional methods. This is the first reported food safety application of genome sequencing on a portable device.
