PathoGenetix and the US Department of Agriculture's Agricultural Research Service (USDA-ARS) will collaborate on evaluating the firm’s Genome Sequence Scanning (GSS) technology.
The technology is for identifying strains of Shigatoxin-producing E. coli (STECs) and Salmonella enterica.
PathoGenetix's GSS technology identifies microbial DNA from mixtures or from isolates, and automates the process from sample preparation through data analysis to provide information in five hours.
USDA-ARS will provide genetic information and bacterial strains of E. coli and Salmonella and both parties will analyze the strains, as isolates and in mixed cultures.
The strain type information provided by GSS is comparable to pulsed field gel electrophoresis (PFGE), the current standard for pathogen typing in foodborne outbreak investigation and response.
GSS technology is under development for commercial use in the Resolution Microbial Genotyping System expected in 2014 for food safety testing and foodborne illness outbreak investigations.
