Susie Jane Muir 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).

  • Serpulina hyodysenteriae vaccine comprising a tly gene mutant
    Patent number: 6007825
    Abstract: According to the present invention a vaccine can be prepared containing a mutant Serpulina hyodysenteriae which is defective in its production of biologically active hemolysin. The mutation by which Serpulina hyodysenteriae is made defective in its production of hemolytically active hemolysin is established by means of genetical engineering techniques. Such mutations comprise e.g. deletion of part or the entire gene coding for hemolysin and/or nucleotide sequences controling the production of hemolysin, or insertion of an extra nucleotide or polynucleotide into the gene encoding hemolysin and/or the nucleotide sequences controling the production of hemolysin, or a combination of said deletion and insertion. These vaccines are useful in the prevention of Serpulina infections in susceptible animals such as swine.
    Type: Grant

  • Treponema hyodysenteriae vaccine
    Patent number: 5364774
    Abstract: The present invention is concerned with vaccine for combating Treponema hyodysenteriae infection in swine containing proteins or polypeptides typical of the hemolysin protein of Treponema hyodysenteriae or containing recombinant polynucleotides having as part thereof a polynucleotide coding for said protein or polypeptide, and also is concerned with the preparation of said proteins, polypeptides and polynucleotides.
