MENLO PARK, Calif., Jan. 8, 2013 (GLOBE NEWSWIRE) — Pacific Biosciences of California, Inc. (Nasdaq:PACB) provider of the PacBio® RS High Resolution Genetic Analyzer, and the University of California, Davis (UC Davis) today announced a partnership for the 100K Pathogen Genome Project. As part of the project, Pacific Biosciences’ Single Molecule, Real-Time (SMRT®) technology will be used to sequence the genomes from at least 1,000 foodborne pathogen samples to completion, and to elucidate their epigenomes. These bacteria represent major illness-causing pathogens, including Salmonella, Campylobacter, E. coli, Vibrio, and Listeria.
The 100K Genome Project was founded by the U.S. Food & Drug Administration, Agilent Technologies, and the laboratory of Dr. Bart Weimer at UC Davis to create a consortium of partners from around the world that will sequence 100,000 foodborne pathogens using next-generation sequencing. This initiative addresses a significant shortage of bacterial pathogen information for use in designing molecular diagnostics, creates a resource to expand our understanding of infection mechanisms, and constructs a public repository for new insights into bacterial evolution by using large-scale genomics.
Pacific Biosciences’ SMRT sequencing technology generates sequence reads an order of magnitude longer than other leading DNA sequencing technologies, thereby facilitating efficient de novo microbial genome assemblies. Long reads are critical for resolving genetic complexity in the assembly and finishing of genomes. The use of SMRT sequencing for the automated finishing of microbial genomes has been demonstrated in multiple recent publications, including for the genetic analysis of the Haitian cholera and German E. coli outbreaks.
The kinetic information acquired during SMRT sequencing can be used to elucidate the epigenome of bacteria. Epigenetic DNA base modifications, such as methylation, play an important role in the phenotypic variation, adaptability and pathogenicity of many bacteria, but they have been difficult to study due to the lack of a sequencing method to detect them. As part of the 100K Genome Project, the epigenomes of the pathogenic strains subjected to SMRT sequencing will be characterized, adding an important dataset to public database repositories.
“SMRT sequencing has been shown to be a powerful technology for the comprehensive determination of microbial genomes and epigenomes,” said Dr. Jonas Korlach, Chief Scientific Officer of Pacific Biosciences. “Through the combination of long reads, high consensus accuracy, and the lack of sequencing bias to GC content or sequence contexts, SMRT sequencing harbors the necessary requirements to construct finished genomes in an unbiased, hypothesis-free manner. The ability to detect methylation as part of the sequencing process is unique to SMRT sequencing, and will provide an invaluable resource to illuminate the epigenetic components controlling bacterial pathogenicity.”
“We are very pleased to utilize SMRT sequencing as part of the 100K Genome Project,” said Bart Weimer, Professor and Director of the 100K Genome Project, “SMRT technology will enable production of complete genomes that will contribute great value toward databases for biological insight, new biomarker discovery, and reference genomes for food pathogen detection. A project of this scale is needed since microbial genome variations, including structural variations, the acquisition and loss of mobile elements, and phages or plasmids, are very difficult or impossible to detect without a de novo sequencing and genome assembly approach, yet they have a significant impact on food safety.”
The partnership will entail the sequencing of at least 1,000 samples by the 100K consortium member labs with access to the PacBio RS instrumentation, including pipeline constructions for high-throughput pathogen sequencing, de novo genome assemblies, epigenome determination, and data curation and deposition. Pacific Biosciences will provide technical guidance and training to support these activities, and interface closely with the involved laboratories to assist in the efficient construction of these pipelines.

About The 100K Genome Project
Established in March 2012 by UC Davis, Agilent Technologies and the U.S. Food and Drug Administration, the 100K Genome Project is a landmark consortium that addresses the persistent food safety concerns by engaging world-wide partners to create a publicly available genetic database of the most common foodborne disease-causing microbes. By sequencing 100,000 pathogen genomes, the project will bring a new paradigm to public health to empower precise and robust molecular testing in the food chain — from the farm to the kitchen table.
