Abstract: The invention relates to a method for identifying and selecting a gene required for the proliferation in vivo of a pathogenic microorganism, comprising:—using a strain of the pathogenic microorganism,—generating mutants for inactivation in the genes encoding these factors,—determining the virulence of these mutants on an experimental model of infection, and their effect on enteric colonization in an axenic mouse model, and—selecting the bacterial genes essential for resistance to serum in vitro, and essential, in the host, for dissemination in the serum. Application to the screening of compounds which inhibit the products of the genes identified, and to the inhibition in vitro of the proliferation of a pathogenic microorganism in serum.

Abstract: The invention relates to compositions of polypeptides specific to pathogenic strains comprising at least one polypeptide of a first group, having a sequence selected in the group comprising the sequences of SEQ ID No 159, or homologous sequences of polypeptides of the first group and/or the second group with a minimum of 25% of identity with the whole sequences of said polypeptides. Application for the preparation of vaccine compositions specific to E. coli extra-intestinal infections.

Abstract: The invention relates to isolated antigenic polypeptides obtainable by a process comprising the steps of: 1—selecting on the basis of sequence analysis those of the polypeptides which are either located in the outermembrane or secreted by the bacteria, 2—identifying the genes coding for said polypeptides which are conserved in B2/D clinical isolates, 3—purifying the polypeptides identified in step 1, which are found in step 2 to be conserved in B2/D isolates, 4—testing the polypeptides for immunogenicity using animals models. Application for making vaccines compositions and immunotherapies.

Abstract: Group B streptococcus is an important cause of maternal and neonatal morbidity and mortality in many part of the world. The invention is a method of identification of novel targets for inhibitors preventing septicemic dissemination of Streptococcus agalactiae, a model of Gram positive bacteria, in order to treat bacterial infections using these virulence determinant.
