  • Nucleotide sequences and methods for detection of Serpulina hyodysenteriae
    Patent number: 6068843
    Abstract: The invention provides a method for detecting the presence of Serpulina hyodysenteriae in a biological sample, an oligonucleotide primer and an S. hyodysenteriae-specific oligonucleotide probe useful in that method, and an article of manufacture that contains the primers and/or probe. Also provided are an about 2.3-kb DNA fragment derived from genomic DNA of S. hyodysenteriae and encoding for an about 56 kDa polypeptide, a recombinant expression vector containing the DNA fragment, the 56 kDa polypeptide and a monoclonal antibody reactive with the peptide, and a method of assaying for antibodies reactive with the 56 kDa peptide.
    Type: Grant
    Filed: October 2, 1997
    Date of Patent: May 30, 2000
    Assignee: Board of Regents University of Nebraska
    Inventors: Gerald E. Duhamel, Robert Elder
