University of Georgia food microbiologist Xiangyu Deng’s work in the emerging field of bioinformatics led to his selection as a Creative Research Medal winner for 2017.
The medal is one of the prestigious honors bestowed annually by the UGA Research Foundation. Awards are given to outstanding faculty, postdoctoral fellows and graduate students in recognition of excellence in research, scholarly creativity and technology commercialization at UGA.
Deng, an assistant professor of food microbiology with the Center for Food Safety (CFS) on the UGA Griffin campus, was recognized for creating a cloud-based software tool that quickly classifies strains of salmonella, one of the most prevalent foodborne pathogens in the United States and worldwide. The Centers for Disease Control and Prevention (CDC) estimates that 1 million foodborne illnesses and 380 deaths in the U.S. each year can be linked to nontyphoidal salmonella.
The SeqSero system identifies serotypes, or distinct strains of salmonella, from infected humans, animals, foods and the environment using whole genome sequencing. This system allows for accurate, fast “fingerprinting” of any salmonella strain and replaces a complicated, time-consuming laboratory protocol. Analysis time using SeqSero takes just minutes — analysis using the old system took days — while adding no extra cost.
