Upon administration to a mammal the vaccine stimulates synthesis of antibodies which are cross-protective against smooth and rough forms of LPS from at least two different Gram-negative bacterial strains having different core structures.Type: GrantFiled: April 25, 2000Date of Patent: June 15, 2004Assignee: Medical Defense Technology, LLCInventors: Elliott Bennett-Guerrero, George Robin Barclay, Ian Raymond Poxton, Thomas James McIntosh, David Scott Snyder

Patent number: 6737063Abstract: The present invention provides bacterial immunogenic agents for administration to humans and non-human animals to stimulate an immune response. Also provided are methods for vaccination of mammalian species, especially human patients, with variants of the E. coli FimH protein, said variants being derived from different strains of E. coli, and to production of antibodies that protect the vaccine recipient against infection by pathogenic bacterial species. In another aspect the invention provides antibodies against such proteins and protein complexes that may be used as diagnostics and/or as protective/treatment agents for pathogenic bacterial species. A plasmid-based method of producing polypeptides, especially fused polypeptides, such as the complex of a bacterial chaperone and a bacterial adhesin, is also disclosed.Type: GrantFiled: July 6, 2001Date of Patent: May 18, 2004Assignee: MedImmune, Inc.Inventors: Solomon Langermann, Andrew Revel, Christine Auguste, Jeanne Burlein

Publication number: 20040086513Abstract: The present invention relates to antibodies immunologically specific for an attaching and effacing Escherichia coli (AEEC) virulence-associated protein, products, compositions and methods and to their use thereof in the prevention of an AEEC infection in a mammal. The antibody of the invention is immunologically specific for an AEEC virulence-associated protein and is capable of preventing an in vivo AEEC intestinal infection when administered to a mammal. The antibody of the invention is preferably useful for preventing the development of A/E intestinal lesions associated with the AEEC. This is achieved by preferably using IgY antibodies immunologically specific for one or more AEEC virulence-associated proteins, such as Eae, Tir, EspA and Paa.Type: ApplicationFiled: November 12, 2003Publication date: May 6, 2004Inventors: John M. Fairbrother, Josee Harel, Isabelle Batisson, Francis Girard, Marie-Pierre Guimond

Patent number: 6713059Abstract: The present invention relates to an immunogenic conjugate comprising a carrier molecule coupled to an autoinducer of a Gram negative bacteria. The immunogenic conjugate, when combined with a pharmaceutically acceptable carrier, forms a suitable vaccine for mammals to prevent infection by the Gram negative bacteria. The immunogenic conjugate is also used to raise and subsequently isolate antibodies or binding portions thereof which are capable of recognizing and binding to the autoinducer. The antibodies or binding portions thereof are utilized in a method of treating infections, a method of inhibiting autoinducer activity, and in diagnostic assays which detect the presence of autoinducers or autoinducer antagonists in fluid or tissue samples.Type: GrantFiled: April 11, 2002Date of Patent: March 30, 2004Assignee: University of RochesterInventors: Andrew S. Kende, Barbara H. Iglewski, Roger Smith, Richard P. Phipps, James P. Pearson

Patent number: 6652857Abstract: The present invention includes methods for generating neutralizing antitoxin directed against verotoxins. In preferred embodiments, the antitoxin directed against these toxins is produced in avian species using soluble recombinant verotoxin proteins. This antitoxin is designed so as to be administrable in therapeutic amounts and may be in any form (i.e., as a solid or in aqueous solution). These antitoxins are useful in the treatment of humans and other animals intoxicated with at least one bacterial toxin, as well as for preventive treatment, and diagnostic assays to detect the presence of toxin in a sample.Type: GrantFiled: June 16, 1999Date of Patent: November 25, 2003Assignee: Promega CorporationInventors: James A. Williams, Lisa Marie Byrne, Charles S. G. Pugh

Patent number: 6605272Abstract: The present invention relates to zalpha11 Ligand polynucleotide and polypeptide molecules. The zalpha11 Ligand is a novel cytokine. The polypeptides may be used within methods for stimulating the proliferation and/or development of hematopoietic cells in vitro and in vivo. The present invention also includes methods for producing the protein, uses therefor and antibodies thereto.Type: GrantFiled: August 3, 2001Date of Patent: August 12, 2003Assignee: ZymoGenetics, Inc.Inventors: Julia E. Novak, Scott R. Presnell, Cindy A. Sprecher, Donald C. Foster, Richard D. Holly, Jane A. Gross, Janet V. Johnston, Andrew J. Nelson, Stacey R. Dillon, Angela K. Hammond
