Stomp Out Salmonella
The Centers for Disease Control and Prevention (CDC) estimates that 1 million foodborne illnesses and 380 deaths in the United States each year can be linked to nontyphoidal salmonella. University of Georgia food microbiologist Xiangyu Deng was awarded the 2017 Creative Research Medal for creating a cloud-based software that quickly classifies strains of salmonella. The SeqSero system uses whole genome sequencing to identify particular strains of salmonella, from infected humans, animals, foods and the environment. This system allows for quick and accurate label of any salmonella strain and replaces a complicated, time-consuming laboratory protocol that took place before the invention.
“This is a highly desirable bioinformatics system and allows for push-button, fast, straightforward and accurate identification of salmonella serotypes from raw data that comes directly off sequencers,” Deng said. “There are more than 2,500 serotypes described for salmonella, and SeqSero focuses primarily on more common serotypes while also being able to ID many rare serotypes.”
The software is being used by the CDC, the U.S. Food and Drug Administration, USDA, multiple state health departments, and more than 20 regulatory agencies in European, Asian, and North American countries.
The research was funded by NIFA’s Hatch funding. Read more about Deng’s invention Want to read about more impacts like this? Check out Fresh from the Field, a weekly bulletin showcasing transformative impacts made by grantees funded by NIFA..
