The conventional scientific process for identifying bacteria’s family – known as serotyping – can be time consuming. For salmonella, it used to take three days, and in some cases more than 12 days to assign a final classification for complex servovars.
As reported by the Cornell Chronicle, researchers from Cornell, the Mars Global Food Safety Center in Beijing, and the University of Georgia have developed a method for completing whole-genome sequencing to determine salmonella serotypes in just two hours and the whole identification process within eight hours.
Their research was published Feb. 24 online in the Journal Food Microbiology.
