Neogen Corporation has announced the development of a detection and identification technology that provides DNA-specific test results for pathogenic serotypes of Salmonella.
Neogen’s new NeoSeek™ pathogen DNA identification method for Salmonella can provide genomic-based serotypes (e.g., Salmonella enterica Enteritidis and Salmonella enterica Heidelberg) in as little as 72 hours from suspected Salmonella positive isolates. The serotypes identified by the NeoSeek service include all of the “top 30” Salmonella serotypes identified by the Centers for Disease Control and Prevention as being the leading causes of human Salmonella infections since the agency instituted its national surveillance program for Salmonella in 1962.
“The rapid detection and identification of specific strains, or serotypes, of Salmonella can be critical to preventing foodborne illness, or rapidly responding to an existing outbreak,” says Ed Bradley, Neogen’s vice president for food safety. “NeoSeek’s Salmonella serotyping service provides a much quicker, definitive alternative to the conventional biochemical identification of Salmonella serotypes from presumptively positive Salmonella isolates.”
The NeoSeek Salmonella serotyping method was developed through a close collaboration with Dr. Jean Guard of the U.S. Department of Agriculture’s Agricultural Research Service. The process enables seamless identification of Salmonella serotypes from Next Generation DNA sequencing data generated by Neogen’s GeneSeek genomics laboratory in Lincoln, NE.
