  • Publication number: 20110318776
    Abstract: This invention relates to a method for identifying germs in a liquid medium, comprising adding a membrane detergent to the liquid medium containing components of a host infected with germs, i.e. cellular components and proteins from the extracellular environment, so as to release the germs from these components without degrading them, and in that the germs that have grown in the liquid medium are analysed by MALDI-TOF MS.

  • Publication number: 20090298713
    Abstract: The present invention relates to products which are of nature B2+ A?, isolated from E. coli, and to their biological applications, in particular their medical (therapeutic, vaccine and diagnostic) and biotechnological applications. In the present application, the expression “of nature B2+ A?” is intended to mean presence at a frequency greater than 10% among the E. coli strains of group B2 of the ECOR collection, and at a frequency of less than 10% among the strains of group A of the same collection. A phylogenic determination method which makes it possible to rapidly and easily distinguish the groups A, B1, B2 and D of the E. coli species with more than 99% precision is in particular described.
