Conference: Genomes 2008 (11 th April) - S8

Session opened with Erick Denamur talking about insertion and deletion hotspots of E.coli. He also talked about the coliscope consortium which is "a sequencing project for the understanding of commensalism and virulence emergence in the Escherichia coli/Shigella species". Then the mic was handed to Carmen Buchrieser who highlighted the importance of Legionella which made the Queen run back to the palace. The following talk was from Tim Stinear who mentioned how poking finger(s) into fish can lead to Mycobacterium marinum (which along with M.ulcerans, is closest to M.tuberculosis giving positive mantoux test) infection! He also mentioned about Gene Spaghetti a cool tool for "visualizing base and amino acid usage in a genome", COG's 3-way genome blast approach and synteny map generation. Model of successive binary fission in E. coliImage via WikipediaThen came Marrion karrasch who talked about ERA-NET PathoGenoMics, Interferon interference (?), invasive propeties of C.albican (with liver capsule invasion as an example) and RNAi for possible therapeutic approach (?). Again thanks to Swati for the better notes below:

Population phylogenomics of the E.coli species
Erick Denamur, medical faculty Xavier Bichat, Paris

- Phylogeny of complete genome within species.

- Majority of E.coli strain can be assigned to one of 4 main phylogenetic groups (A, B1, B2 and D).

- These 4 phylogenetic groups differ in their phenotypic and genotypic characteristics.

- Gene conversion doesn’t affect the tree topology.

- E.coli ancestor is close to K-12
