Abstract: Novel compositions are disclosed for use in the treatment or diagnosis of bovine pasteurellosis, commonly referred to as Shipping Fever. Cell-free Pasteurella haemolytica supernatants are employed to provide individual antigen compositions, identified through reaction with sera from naturally-infected or convalescent cattle. In particular, at least seven individual P. hameolytica antigen groups were recognized in cell-free culture supernatants. Purified P. haemolytica supernatant, formulated in a suitable pharmaceutical vaccine composition is shown to elicit a specific immune response, in both cows and rabbits, directed against the individual immunoreactive P. haemolytica polypeptides identified. Also disclosed are novel recombinant cells, plasmids and bacteriophage which include transcriptionally active P. haemolytica antigen genes. Recombinant clones are similarly selected to be reactive with naturally-infected antisera.

Abstract: The invention relates to a fully solubilizable fibrin based composition, which is characterized by the combination that the fibrin is desAA-fibrin or desAA-fibrin from which the C-terminal portions of the .alpha.-chains have been removed by enzymatic digestion, and that the solubilizing agent is a tetrapeptide containing the amino acid sequence -L-prolyl-L-arginyl-, preferably glycyl-L-prolyl-L-arginyl-L-prolin.The full solubility of the fibrin makes possible new uses within the area of determination of important fibrinolytical parameters, and the invention also relates to three such important alternative uses. A first use according to the invention is the use of the composition in connection with detection or quantification of the activity of the enzyme tissue plasminogen activator.

Abstract: The present invention relates to methods which utilize anti-idiotypic antibodies, or fragments thereof, for tumor immunotherapy or immunoprophylaxis. Monoclonal anti-idiotypic antibodies which recognize an idiotype present on a second antibody or on a T lymphocyte or on an immune suppressor factor which is directed against a defined tumor antigen, can be used for immunization against a tumor, for immune anti-tumor activation or inhibition of suppression, or for in vitro activation of lymphocytes to be used in adoptive immunotherapy. The anti-idiotypic antibodies, or fragments thereof, can also be used to monitor anti-antibody induction in patients undergoing passive immunization to a tumor antigen by administration of anti-tumor antibody. In another embodiment, administration of T lymphocytes which express an idiotype directed against a defined tumor antigen can be used to transfer delayed-type hypersensitivity to the tumor.

Abstract: The present invention provides novel hybridoma cell lines which produce monoclonal antibodies (MoAbs) that bind epitopes found on lipopolysaccharide most commonly associated with the endotoxin core of gram negative bacteria and exhibit broad cross-reactivity with gram negative bacteria of different genera and effectively neutralize endotoxin. At least one of the MoAbs disclosed (XMMEN-J5D) binds an epitope also found on gram positive bacteria. The hybridomas are produced by fusing an immortal cell, a cell having the ability to replicate indefinitely in myeloma cell culture, and an effector immune cell following immunization of the immune cell host with a preparation of a gram negative bacteria. While several individual hybridoma cell lines producing monoclonal antibodies to lipopolysaccharide are described, the present invention adds to the state of the art an entire family of hybridoma producing monoclonal antibodies to lipopolysaccharide-associated epitopes.
