Abstract: The present invention relates to a bacterial strain of the Faecalibacterium prausnitzii species selected from a bacterial strain belonging to one of the phylogroups I, II and III, for use in the treatment and/or prevention of visceral abdominal pain in an individual. The present invention also concerns compositions comprising said bacterial strains as well as specific strains as such.

Abstract: The present invention relates to the preventive or curative treatment of metabolic syndrome and associated disorders, and inflammatory bowel diseases using Coprococcus bacteria and/or culture supernatants thereof.

Abstract: The present invention relates to the preventive or curative treatment of metabolic syndrome and the associated disorders with AhR agonist or microorganism producing AhR agonist.

Abstract: The present invention relates to an association of a bacterial strain of the species Faecalibacterium prausnitzii deposited with the CNCM under accession number CNCM I-4573 with mesalamine, or a derivative thereof, and in particular to the use of this association in the treatment and/or prevention of an inflammatory gastrointestinal disease in an individual.

Abstract: A method for treating a gluten-induced disease, such as celiac disease, in a subject in need thereof is provided. The method comprises administering to the subject at least one agent that activates aryl hydrocarbon receptor such as AhR agonists, bacterial probiotics with AhR agonist activity, and IL-22 agonists, polypeptides and nucleic acid.

Abstract: The invention relates to a method comprising a step of determining the number, concentration and/or proportion of T lymphocytes with a CD4+ CD8??low phenotype and further expressing CCR6 and/or CXCR6, for (i) diagnosing, (ii) prognosing outcome of, or (iii) predicting the risk of developing a disease related to a decrease of F. prau. The invention also concerns the treatment of said disease by administering a population of these specific T lymphocytes. The Inventors have indeed identified two markers, CCR6 and CXCR6, enabling to select a population of F. prau-specific cells among CD4+ CD8??low T lymphocytes, from a blood sample and without needing to assess their F. prauspecificity. T lymphocytes with a CD4+ CD8??low CCR6+ CXCR6+ phenotype are for example significantly decreased in IBD patients. The disease related to a decrease of F. prauis particularly an inflammatory bowel disease (IBD), such as Crohn's disease.

Abstract: A method for preventing or treating an inflammatory disease, such as inflammatory bowel disease and Crohn disease, is presented. The method includes administering to a patient a polypeptide having the amino acid sequence of SEQ ID NO: 1, a conservative derivative or a fragment thereof, a nucleic acid sequence encoding said polypeptide, a vector comprising said nucleic acid sequence or a host cell that has been transfected, infected or transformed by said nucleic acid sequence and/or by said vector.

Abstract: The invention relates to a bacterial strain of species Faecalibacterium prausnitzii deposited at the CNCM under access number CNCM I-4573, for use in the treatment and/or prevention of an inflammatory gastrointestinal illness in an individual.

Abstract: The present invention relates to methods for prognosing and treating metabolic diseases. The inventors demonstrated the association of obesity with the increase of intestinal IDO activity, which shifts tryptophan (Trp) metabolism from indole derivative but also IL-22 production towards kynurenine (Kyn) production. The inventors showed that the rewiring of Tip metabolism is possible towards a microbiota-dependent production of IL-22.

Abstract: The present invention relates to a bacterial strain of the Faecalibacterium prausnitzii species selected from a bacterial strain belonging to one of the phylogroups I, II and III, for use in the treatment and/or prevention of visceral abdominal pain in an individual. The present invention also concerns compositions comprising said bacterial strains as well as specific strains as such.

Abstract: The present invention relates to methods and pharmaceutical compositions for preventing or treating inflammatory bowel diseases.

Abstract: The invention relates to a fecal microbiota sample for use in the prevention and/or treatment of infectious or non-infectious complications resulting from allogeneic hematopoietic stem cell (HSC) transplantation, or for the treatment of cancer in a recipient patient, said fecal microbiota sample and said hematopoietic stem cells originating from the same donor subject, or said fecal microbiota sample being administered prior to HSC transplantation.

Abstract: The present invention relates to the use of at least one Lactobacillus bacterium, or a composition comprising thereof or conditioned thereby, for decreasing a population of Bilophila wadsworthia or inhibiting the growth thereof

Abstract: The present invention relates to a bacterial strain of the Faecalibacterium prausnitzii species selected from a bacterial strain belonging to one of the phylogroups I, II and III, for use in the treatment and/or prevention of visceral abdominal pain in an individual. The present invention also concerns compositions comprising said bacterial strains as well as specific strains as such.

Abstract: The present invention relates to the preventive or curative treatment of metabolic syndrome and the associated disorders with AhR agonist or microorganism producing AhR agonist.

Abstract: The invention relates to a bacterial strain of species Faecalibacterium prausnitzii deposited at the CNCM under access number CNCM I-4573, for use in the treatment and/or prevention of an inflammatory gastrointestinal illness in an individual.

Abstract: The present invention relates to methods and pharmaceutical compositions for preventing or treating inflammatory bowel diseases.

Abstract: The present invention relates to a composition comprising a therapeutically effective amount of Bacteroides thetaiotaomicron or an extract thereof for use in the prevention or treatment of an infection in a subject who is immunodepressed, who is immunosuppressed, who has an immature immune system, and/or who has a weakness, and in which the composition comprises at most six species of bacteria and/or extracts thereof. The infections concerned are mainly intestinal infections, in particular those which affect non-human mammals and/or humans.

Abstract: A method for preventing or treating an inflammatory disease, such as inflammatory bowel disease and Crohn disease, is presented. The method includes administering to a patient a polypeptide having the amino acid sequence of SEQ ID NO: 1, a conservative derivative or a fragment thereof, a nucleic acid sequence encoding said polypeptide, a vector comprising said nucleic acid sequence or a host cell that has been transfected, infected or transformed by said nucleic acid sequence and/or by said vector.

Abstract: A polypeptide including or consisting of the amino acid sequence SEQ ID NO: 1, for use in the treatment or prevention of an inflammatory disease. A nucleic acid sequence encoding the polypeptide, a vector including the nucleic acid and a host cell including the nucleic acid sequence and/or a vector, for use in the treatment or prevention of an inflammatory disease are also described. A pharmaceutical composition including the polypeptide, the nucleic acid sequence, the vector or the host cell and a pharmaceutically acceptable carrier, for the treatment of inflammatory disease are also disclosed.
