  • Detection, isolation and identification of microorganisms
    Patent number: 10745735
    Abstract: A method of selectively identifying live microorganisms in a sample involves contacting a sample suspected of containing a live microorganism of interest with a biomolecular precursor labeled with a reactive chemical label. The live microorganism of interest is grown under conditions that promote selective growth of the microorganism to permit the microorganism to utilize the labeled biomolecular precursor to synthesize labeled biomolecules on a cell surface of the live microorganism. Labeled live microorganisms are contacted with a reporter and/or capture element bearing a functional group that reacts with the reactive chemical label. The labeled live microorganism is analyzed to identify it. The method can specifically isolate live microorganisms from dead ones thereby reducing the possibility of false identification of contaminating microorganisms and is able to detect specific strains using tailored metabolites that are specific for a given microorganism.
