  • Patent number: 10119967
    Abstract: The present invention provides kits and assay methods for the early detection of pathogens, precise identification of the etiologic agent, and improved disease surveillance. More specifically, the present invention discloses an immunoassay leading to the rapid and simultaneous detection of antibodies to a wide range of infectious pathogens in biological fluids of infected patients. This immunoassay involves the covalent and oriented coupling of fusion proteins comprising an AGT enzyme and a viral antigen on an identifiable solid support (e.g. fluorescent microspheres), said support being previously coated with an AGT substrate. This coupling is mediated by the irreversible reaction of the AGT enzyme on its substrate. The thus obtained antigen-coupled microspheres show enhanced capture of specific antibodies as compared to antigen-coupled microspheres produced by standard amine coupling procedures.

  • Patent number: 10036074
    Abstract: This invention is related to the area of characterization of inflammation in relation with the gut microbiota, in metabolic and autoimmune disorders. In particular, it relates to the identification of gene signatures which can be used as a marker predictive of inflammation associated diseases, such as liver-related metabolic disorders, in particular to the evolution of benign steatosis towards its most severe forms (steatohepatitis and cirrhosis) or autoimmune disorders, in particular inflammatory bowel diseases (Crohn's and Ulcerative Colitis). These gene signatures can therefore be used as a means of diagnosis, prognosis, stratification for drug studies, for monitoring patient and for assigning an appropriate treatment.

  • Publication number: 20180137236
    Abstract: A system, method, computer readable medium and device for identifying discriminant spectrum clusters including receiving known input data set comprising spectra generated from biological samples known to either have or not have a biological condition where each spectrum may be either known to have been generated from the biological samples known to have or a biological condition, or from the biological samples known not to have same. A software module may apply quality control filters to the input data set to exclude spectra that do not meet the quality control filters, generate a set of remaining spectra, cluster same into a set of spectrum clusters by applying clustering parameters, and identify a set of discriminant spectrum clusters by examining whether each spectrum cluster exclusively contains only spectra generated from samples known to have a biological condition or exclusively contains spectra from samples known not to have the biological condition.
