Rapid Identification and Strain Typing of Salmonella in Food Using Genome Sequence Scanning Technology
Date:5/30/2013

Woburn, MA (PRWEB) May 30, 2013

PathoGenetix, Inc., a commercial-stage developer of an automated system for rapid bacterial identification, has announced new research demonstrating the use of Genome Sequence Scanning™ (GSS™) technology to confirm and identify pathogenic Salmonella strains in enriched spinach samples in less than five hours. The study findings were detailed in a poster presented last week at the General Meeting of the American Society for Microbiology in Denver.

The results demonstrate the ability of GSS to shorten the time for pathogen subtyping and serotype determination from an enriched food sample, and to quickly derive additional strain and serotype information from the numerous pathogen screening tests commonly used in the food industry. Because GSS isolates and scans microbial DNA directly from a mixed culture and does not require a pure culture isolate, it greatly reduces the time, complexity, skill and cost required by other molecular and whole genome identification approaches. As a result, GSS can enable quicker decisions affecting food safety and public health. The GSS technology will be commercially available in 2014 in the RESOLUTION™ Microbial Genotyping System.

The research spiked ten common Salmonella strains in leafy spinach greens including multiple serotypes of Typhimurium and Enteritidis, as well as the Javiana, Newport, Montevideo and Heidelberg serotypes. The test samples modeled “pre
