  • Biocides
    Publication number: 20080274095
    Abstract: The present invention relates to the use of biocide (e.g., bactericidal enzyme) to target pathogens. In particular, the present invention provides biocides for use in health care (e.g., human and veterinary), agriculture (e.g., animal and plant production), and food processing (e.g., water purification).

  • Neutralization-sensitive epitopes of Cryptosporidium parvum
    Patent number: 6759048
    Abstract: DNA sequences encoding epitopes to which sporozoite-neutralizing antibodies are directed are provided. Recombinant proteins and synthetic peptides containing Cryptosporidium parvum epitopes for inducing an antigenic response are described.
    Type: Grant
    Filed: September 6, 2001
    Date of Patent: July 6, 2004
    Assignees: North Carolina State University, Arizona Board of Regents, Washington State University Regents
    Inventors: Lance E. Perryman, Douglas P. Jasmer, Michael W. Riggs, Travis C. McGuire
  • Anti-cryptosporidium parvum preparations
    Patent number: 6730307
    Abstract: Compositions and methods useful for conferring passive or active immunity to the parasite, C. parvum. A high molecular weight glycoprotein antigen isolated from C. parvum, capable of binding the mAb 3E2, was shown to harbor an epitope critical for triggering the neutralizing CSP-like reaction in the parasite. Antibodies targeted against the critical epitope were shown to possess neutralizing activity, and could be combined with other anti-C. parvum monoclonal antibodies and administered to an animal to confer passive immunity. Immunogenic compositions including the purified antigen are disclosed for use in stimulating an active immune response against C. parvum.
