The complete map of the Germany E. coli O104 genome released
Date:6/16/2011

so identified in the research. This indicates that horizontal gene transfer events may have played important roles in the evolution of virulence and drug resistance of this strain.

The results of these and previous phylogenetic and comparative genomic analyses now give us the confidence to confirm that the outbreak strain belong to an EAEC (enteroaggregative E. coli) lineage, but acquired the Shiga toxin producing ability by the integration of a phage genome. This explains the initial confusion as to why the EAEC-lineage bacteria harbored some characteristics of EHEC (enterohaemorrhagic E. coli) strains. Therefore, the deadly Germany E. coli is not a completely new bacteria and can be considered a "hybrid" strain, now temporarily termed Shiga toxin-producing enteroaggregative Escherichia coli (STpEAEC).

BGI has a new portal collecting most of the genomic evidence, and due to the urgency in fighting the outbreak, BGI's data has been released under a public domain license. To aid the growing crowdsourcing effort this is accessible for the first time via a data DOI a digital object identifier that allows citation of a dataset before formal publication. These novel ways of freely and publicly releasing of information has allowed unprecedentedly rapid progress in understanding the genomic insights of this infection, and a growing team of researchers have now confirmed they will also release their work in the same manner (see: http://bacpathgenomics.wordpress.com/2011/06/13/e-coli-data-released-under-creative-commons-0-license/). Please see the Github repository for the latest open research by the E. coli community and our portal page:
