  • Publication number: 20230201326
    Abstract: The invention is directed to portions of proteins of gram-positive bacteria, gram-negative, acid-fast bacteria (Mycobacteria, Staphylococcus) and/or virus (SARS-COV-2, Influenza), and antibodies reactive against these portions that can be formulated as immunogenic compositions and vaccines for the treatment and prevention of a microbial and/or viral infections. Preferably, compositions of the invention contain one or more portions of selected microbial and/or viral proteins that, upon administration to a subject, generate an effective cellular and/or humoral immune response, modulate immunity and a cytokine response. Effective responses involve an increased generation of antibodies that enhance immunity against an infection and promote an enhanced a phagocytic response. Monoclonal antibodies produced against these peptides enhance phagocytosis and killing of bacteria, viruses, and other microbes by phagocytic cells, and enhance clearance from the blood.

  • Publication number: 20220088166
    Abstract: The invention is directed to compositions and methods for stimulating, enhancing or modulating the immune system of a patient before or after infection by a pathogen, and in particular multidrug resistant (MDR) MTB and extremely drug resistant (XDR) MTB. Compositions of the invention contain non-naturally occurring antigens that generate an effective cellular and/or humoral immune response to MTB and/or antibodies that are specifically reactive to MTB antigens. The greater activity of the immune system generated by a vaccine of the invention increases generation of memory T cells that provide for a greater and/or extended response to an MTB infection. Responses involve an increased generation of antibodies that enhance immunity against MTB infection and promote an enhanced phagocytic response.

  • Publication number: 20210381032
    Abstract: Disclosed is an enhanced method for rapid and cost-effective analysis of sequences of a microorganism by qPCR. These methods identify allelic variation, SNPs, and genetic mutations of a particular gene such as those responsible for conferring resistance or sensitivity to an antibiotic, chemotherapy, or another chemical compound. By selection of appropriate gene regions, mutation loci that confer resistance to key antibiotics can be identified by qPCR. Additionally, the approach can identify heteroresistant strains, e.g., populations of strains from a sample that contain both mutation and wild-type nucleotides. By selecting appropriate that bind efficiently to the area of mutation can identify resistance conferring mutations. Methods are useful to sequences derived from viral agents, such as influenza virus, bacterial agents, such as tuberculosis bacteria, and cancer cells.

  • Patent number: 11186867
    Abstract: Disclosed is an enhanced method for rapid and cost-effective analysis of sequences of a microorganism by semi-conductor sequencing, preferably ion-torrent sequencing. This method provides for full length analysis and of multiple areas (e.g. genes) of multiple genomes. These methods identify genetic mutations of a particular gene that are responsible for conferring resistance or sensitivity to an antibiotic or other chemical compound. Multiple different species, strains and/or serotypes of a particular organism are rapidly and efficiently screened and mutations identified along with the complete genome of an organism. By selecting primers pairs of similar size and GC content that produce amplicons with sequences spanning the entire genome, a single PCR reaction analyzed by ion torrent methodology can determine the sequence of a complete genome. Methods are useful to sequences the genomes of viral agents, such as influenza virus, and bacterial agents, such as tuberculosis bacteria.
