PathoGenetix to Present Strain Typing Technology and Research Results for Salmonella and Pathogenic E. coli at IAFP

Woburn, MA (PRWEB) July 25, 2013

PathoGenetix™, Inc., a commercial-stage developer of an automated system for rapid bacterial identification, will present the RESOLUTION™ Microbial Genotyping System for the first time at the 2013 International Association for Food Protection (IAFP) Annual Meeting in Charlotte, North Carolina, July 28-31, 2013. The RESOLUTION System, which identifies pathogens in enriched food samples in five hours and provides strain level resolution comparable to pulsed field gel electrophoresis (PFGE), will be demonstrated in the exhibit hall (booth #902) and in private meetings. Two new research studies detailing the differentiation and typing of Salmonella strains, from both pure culture and complex “presumptive positive” food samples, will be presented in IAFP poster sessions.

PathoGenetix also will make available research results demonstrating the use of Genome Sequence Scanning™ (GSS™), the technology underlying the RESOLUTION System, to identify and differentiate virulent Shiga toxin-producing E. coli (STEC). The ability of GSS to reliably differentiate virulent STECs has significant implications for food producers required to test their products for pathogens having certain virulence characteristics. Current screening methods have a high “false positive” rate for detection of Big 6 E. coli due to the commingling of virulence factors that can be present in an enriched food sample. The RESOLUTION System could be used as a confirmatory method for Big 6 STEC screening assays, and potentially reduce the loss of product associated with false positive results from current STEC screening tests.

PathoGenetix’s Genome Sequence Scanning works from complex mixtures or from pure culture isolates, and automates the identification process from sample preparation through data analysis to provide actionable information in five hours. GSS is a breakthrough in microbial identification with broad applicability in food safety, research, industrial microbiology and clinical diagnostics. The RESOLUTION Microbial Genotyping System is the first commercial application of GSS technology, and will be available in 2014 for use in food safety testing and foodborne illness outbreak investigation. PathoGenetix has an agreement to place a beta instrument with one government collaboration partner, and is in discussion with other potential government and industry beta evaluation sites. Performance testing and submission to AOAC of the instrument, assays and protocols is planned for 2014.

The IAFP Annual Meeting provides information on current and emerging food safety issues, and is the leading food safety conference worldwide. PathoGenetix will exhibit the RESOLUTION System at IAFP beginning on Sunday, July 28, at 7:30 PM and continuing through Tuesday, July 30, at 6:00 PM. For more information or to schedule a demonstration of the technology, email info(at)pathogenetix(dot)com.

PathoGenetix research detailing the serotyping and strain typing capabilities of Genome Sequence Scanning in a variety of matrices will be presented at IAFP in two poster sessions on Tuesday, July 30, and Wednesday, July 31.

About PathoGenetix, Inc.

PathoGenetix™, Inc. is a commercial-stage developer of an automated system for rapid bacterial identification from complex samples. PathoGenetix is a venture-backed company that has received more than $50 million in technology development funding from the Department of Homeland Security. The core Genome Sequence Scanning™ (GSS™) technology analyzes DNA from an enriched biological sample—without the need for a cultured isolate—and provides results in five hours. GSS has broad applicability in food safety, industrial microbiology, and clinical diagnostics and research. The GSS technology will be available in the RESOLUTION™ Microbial Genotyping System in 2014 for use in food safety testing and foodborne illness outbreak investigations. Learn more at
