  • Protein composition and methods for analysing microbiota
    Patent number: 11933790
    Abstract: A method of isotope-labelling a microbiota sample. It involves providing a first microbiota sample that was obtained from a given source; exposing the first microbiota sample to an isotope enriched medium; and culturing the exposed first microbiota sample in the isotope enriched medium to obtain an isotope-labelled microbiota sample, wherein the isotope labelled metaproteome of the isotope-labelled microbiota sample is taxon specific for taxa present in the first microbiota sample when initially obtained from the given source.
    Type: Grant
    Filed: January 27, 2021
    Date of Patent: March 19, 2024
    Assignee: UNIVERSITY OF OTTAWA
    Inventors: Joseph Michel Daniel Figeys, Alain Christophe Stintzi, David R. Mack, Xu Zhang, Zhibin Ning

  • MARKERS FOR DISEASE AND DISEASE EXTENT IN INFLAMMATORY BOWEL DISEASE
    Publication number: 20200191803
    Abstract: A method for determining a presence of inflammatory bowel disease in a subject. The method involves providing a gut sample obtained from a subject; measuring a level in said gut sample of one or more proteins, wherein said one or more proteins comprises at least one of: leukotriene A-4 hydrolase, catalase, transketolase, thioredoxin domain containing protein 17, vasodilator-stimulated phosphoprotein and thymosin beta-10; and comparing said measured level of each of said one or more proteins to a corresponding protein level for a normal subject. A method for determining a presence of pancolitis in a subject with ulcerative colitis is also provided.
