  • Patent number: 7955796
    Abstract: Described is a method for the detection and quantification of methicillin-resistant Staphylococcus aureus from a specimen comprising a) contacting the specimen with Anti-Protein A antibodies so as to adsorb methicillinresistant Staphylococcus aureus and/or methicillin-sensitive Staphylococcus aureus, b) separating said antibodies to which methicillin-resistant Staphylococcus aureus and/or methicillin-sensitive Staphylococcus aureus have been adsorbed from the specimen, c) lysing methicillin-resistant Staphylococcus aureus and/or methicillin-sensitive Staphylococcus aureus adsorbed to said antibodies so as to release their DNA, d) combining the released DNA with (i) probes and/or primers which are specific for a target DNA sequence of the mecA gene of methicillin -resistant Staphylococcus aureus and/or of methicillin-resistant Staphylococcus epidermis, (ii) probes and/or primers which are specific for a target DNA sequence of methicillin-resistant Staphylococcus aureus other than a target DNA sequence of the m

  • Publication number: 20070015151
    Abstract: The invention is related to an analytical chip for the simultaneous determination of one or more different bacterial 16S-rRNA in a liquid sample comprising—an evanescent field measurement platform, e.g. an optical waveguide, as a solid carrier and—a plurality of specific recognition elements immobilized in discrete measurement areas of known location forming an array of measurement areas on said evanescent field measurement platform, wherein—a multitude (i.e. 2 or more) of different specific recognition elements is immobilized in discrete measurement areas for the recognition and detection of each different 16S-rRNA, different recognition elements being specific for different subsequences of the 16S-rRNA to be detected, which are not directly adjacent and not overlapping in the sequence of said 16S-rRNA, and—said analytical chip is operable for the detection of 16S-rRNA in the evanescent field of the evanescent field measurement platform, without an amplification (e.g.

  • Patent number: 6544777
    Abstract: The present invention comprises a non-cognate hybridization system (NCHS). The NCHS generally includes a hybridization technology that is simply and economically used to probe for non-cognate nucleic acid sequences, i.e., for nucleic acid strands without known target sequences. NCHS causes nucleic acids, bound to a probe surface, to create a hybridization pattern that provides information about the presence and/or quantity of the nucleic acid sequences in a sample. The NCHS results normally orient the examiner towards a small number of specific diagnoses across a wide variety of diagnostic categories (including but not limited to infections, neoplasms and autoimmune diseases). The test will also identify final-common-pathway syndromes such as sepsis, anaphylaxis and tumor necrosis. While the test utilizes genetic information, it does not depend on prior knowledge of the genes involved in a particular disease or syndrome.
