    摘要： The invention is directed to compositions and methods for rapidly detecting, amplifying, and quantitating one or more pathogen-specific nucleic acids in a biological sample, and in particular, samples obtained from patients with sepsis. The invention also provides diagnostic kits containing specific amplification primers, and labeled detection probes that specifically bind to the amplification products obtained therefrom. The invention is also directed to detecting the quantity or ratio of genomic sequences and mRNA sequences of an individual suspected of being infected with an infectious agent over time to assess the progress of the infection over time. Also disclosed are compositions and methods for the isolation and characterization of nucleic acids that are specific to one or more pathogens, such as, for example, Influenza virus, Mycobacterium tuberculosis, Plasmodium, and/or HIV from a wide variety of samples including those of biological, environmental, clinical and/or veterinary origin.

    摘要： The invention relates to composite antigens comprising an antigen obtained or derived from an antigenic epitope of one or more pathogens that induces an immune response in a mammal, an antigen obtained or derived from bacterial cell wall material that induces an immune response in a mammal such as LTA, PNG or LPS, and a T cell stimulating antigen such as CRM. Preferably the composite antigen comprises an immunogenic composition or a vaccine that is effective against the pathogen or can generate antibodies that can be collected that are protective against infection by the pathogen. In addition, the invention relates to vaccines comprising composite antigens and to method for treating and preventing an infection.

    摘要： The invention relates to immunogenic compositions comprising an antigen obtained or derived from an antigenic epitope of one or more pathogens that induces an immune response in a mammal, an antigen obtained or derived from bacterial cell wall or viral material that induces an immune response in a mammal such as LTA, PNG or LPS, and a T cell stimulating antigen such as CRM. Preferably the immunogenic composition is a vaccine that is effective against a pathogenic infection or can generate antibodies that can be collected that are protective against infection by the pathogen. In addition, the invention relates to vaccines comprising antigens and to method for treating and preventing an infection.
