UCDAVIS-100K Genome Project unveils 20 more foodborne pathogen genomes
July 22, 2013 The 100K Genome Project, led by the University of California, Davis, the U.S. Food and Drug Administration’s Center for Food Safety and Applied Nutrition, and Agilent Technologies, today 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 genomes were determined using Single Molecule, Real-Time (SMRT®) Sequencing technology from Pacific Biosciences of California, Inc.
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 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.
“These finished genome sequences represent the highest quality standard, with each strain closed in a single bacterial chromosome and the associated mobile DNA,” said Bart Weimer, director of the 100K Genome Project and professor at the school of veterinary medicine at UC Davis. “They also contain complete associated phage or plasmid elements, which are critical for understanding pathogenicity, drug resistance and other biologically important traits that are linked to survival.
