Doug Hodgins 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).

  • Modified leukotoxin gene and protein
    Patent number: 7932085
    Abstract: The present invention provides nucleic acid sequences encoding a modified leukotoxin protein, wherein the modification comprises the removal of nucleic acid sequences encoding amino acids within hydrophobic transmembrane domains of full length leukotoxin protein, preferably from Mannheimia haemolytica. The modified leukotoxin proteins are useful in vaccine compositions effective against Mannheimia haemolytica in animals.
    Type: Grant
    Filed: July 9, 2010
    Date of Patent: April 26, 2011
    Assignee: University of Guelph
    Inventors: Reggie Y. C. Lo, Patricia E. Shewen, Raymond W. H. Lee, Doug Hodgins, Judith N. Strommer
