Patents by Inventor Christopher Anthony Przybyszewski

Christopher Anthony Przybyszewski has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20240102027
    Abstract: The inventive subject matter includes an antimicrobial peptide vectored composition made of a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules. More specifically these novel recombinant antimicrobial peptide effector molecules exhibit preferential antimicrobial activity. In some embodiments, the antimicrobial activity is facilitated via interaction with the lipid bilayer of the parasitic cell form, leading to membrane pore formation and resulting in cell lysis. The utility of the current inventive subject matter has demonstrated a reduced viability of Eimeira acervulina sporozoites was shown in vitro using a sporozoite killing assay.

  • Patent number: 11814628
    Abstract: The inventive subject matter includes an antimicrobial peptide vectored composition made of a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules. More specifically these novel recombinant antimicrobial peptide effector molecules exhibit preferential anti-microbial activity. The utility of the current inventive subject matter has demonstrated a reduced viability of Eimeira acervulina sporozoites in vitro using a sporozoite killing assay. More specifically, the antimicrobial peptide vectored composition is a bacterial protein expression vehicle expressing one or more recombinant antimicrobial peptide effector molecules, wherein the one or more recombinant antimicrobial peptide effector molecules are engineered from a NK-lysin gene and the one or more recombinant antimicrobial peptide effector molecules are engineered to express functionally active NK-2.
