Researchers detail 20 more pathogens

By From page A5 | July 26, 2013

The 100K Genome Project has announced that it has added 20 newly completed genome sequences of foodborne disease-causing microorganisms to its public database at the National Center for Biotechnology Information.

The project is led UC Davis, the U.S. Food and Drug Administration’s Center for Food Safety and Applied Nutrition and Agilent Technologies.

The newly deposited sequences include several isolates of Salmonella, Listeria, Campylobacter and Vibrio, as well as a full characterization of their epigenomes: a diagnostic feature that defines how the DNA is chemically modified and changes how the organism behaves.

“The genomes we have analyzed to date are from pathogens responsible for common and debilitating foodborne infections,” said Bart Weimer, project director and professor at the UCD School of Veterinary Medicine.

This brings to 30 the number of genomic sequences completed by the 100K Genome Project, which aims to sequence the genomes of 100,000 bacterial and viral genomes.

This genome sequencing effort is focused on speeding the diagnosis and treatment of foodborne diseases, as well as shortening the duration and limiting the spread of foodborne illness outbreaks. In the United States alone, foodborne diseases annually sicken around 48 million people and kill approximately 3,000, according to the Centers for Disease Control and Prevention.

The 100K Genome Project was launched in March 2012.
