Center for Genomic Epidemiology spinout
June 2016
A spinout company has recently been founded on the basis of Center for Genomic Epidemiology. One of the main activities of the company will be to conduct workshops on the topic of whole genome sequencing and analysis for microbial diagnostics with special focus on the tools developed by Center for Genomic Epidemiology.

Consortium to combat infectious disease outbreaks
January 2015
The COMPARE project has been funded with 20 million Euro from the EU. COMPARE (COllaborative Management Platform for detection and Analyses of (Re-) emerging and foodborne outbreaks in Europe) is a collaboration of founding members of the Global Microbial Identifier (GMI) initiative and institutions with hands-on experience in outbreak detection and response. The COMPARE project will establish a ‘one serves all’ analytical framework and data exchange platform that will allow real-time analysis and interpretation of sequence-based pathogen data in combination with associated data. The Consortium consists of 29 partners with multidisciplinary expertise in human health, animal health and food safety. How to optimally determine taxonomy from whole genome sequences.

Pathogenic bacteria identified and described directly from clinical samples within a day
December 2013
The CGE project has demonstrated how, within the space of a single day, pathogenic bacteria can be identified and described directly from clinical samples. In the long term, this will help doctors treat patients more quickly with the right medicine, thus reducing periods of illness and saving lives.

Internet-Based Solutions for Analysis of Next-Generation Sequence Data
August 2013
As a response to a paper published in Journal of Clinical Microbiology earlier this year, in which the authors wish for user-friendly and clinically focused platforms for analysis of next-generation sequence data, we here highlight the tools that we have already developed and made available, as well as future tools that are currently being developed.

Global Microbial Identifier
December 2012
GMI focuses on the use of genome sequencing techniques in a global system for microbiological identification and epidemiological surveillance.The vision is to develop a global system to aggregate, share, mine and use microbiological genomic data to address global public health and clinical challenges, a high impact area in need of focused effort.

Defining the Pseudomonas Genus: Where do We Draw the Line with Azotobacter?
August 2011
Classifying bacteria is important for keeping track of outbreaks. How does one define a bacterial genus? Azotobacter was originally classified as belonging to the 'Pseudomonas' genus, but then later moved to its own genus, based on phenotypic behavior. Using several different genome-based methods, we find that the Azotobacter is most closely related to Pseudomonas, and perhaps is better understand as a different species within this genus.

Microbial Forensics and Molecular Epidemiology and the Population Genetics of High Homogeneous Bacteria
August, 2011
Paul Keim, Director of The Pathogen Genomics Division, TGen, USA gives a talk on the subject at DTU monday August 15th.
Bacterial pathogens frequently emerge in high virulent waves that sweep across regions, continents or even the globe. Whether this is due to a fitness advantage or simply due to stochastic opportunities isn't always clear, but these populations are highly clonal and highly homogeneous. The analytical challenges include the identification of rare genetic variation to discriminate among isolates and the subsequent genotyping of large sample sets to track the disease. Whole genome sequencing can now identify nucleotide differences, even if vanishingly rare. Genotyping assay development and implementation strategies are many, but need to fit particular applications in expense, speed, and sensitivity. Dr. Keim will discuss the state of this science and give examples from bioterrorism (anthrax), laboratory safety (plague) and public health (cholera).

New paper is published about the Salmonella enterica Pan-genome
June 2011
We have compared 45 sequenced S. enterica genomes that are publicly available (22 complete and 23 draft genome sequences) along with two Escherichia coli strains and estimated the core and pan-genome of Salmonella to be around 2,800 and 10,000 gene clusters, respectively. Pan-genomic dendrograms suggest that gene content is often, but not uniformly correlated to serotype. Any given Salmonella strain has a large stable core, which is extended with an abundance of variable accessory genes, typically localized in specific flexible genomic regions or islands, such as transposable elements, phages, and integrated plasmid DNA. These islands were typically well conserved in some, but not all, isolates - a difference which could have implications in, e.g., host specificity.
