Abstract: Various embodiments of systems and methods for Cross-Site Request Forgery (XSRF) protection are described herein. An XSRF protection framework provides rich configuration possibilities for protection using an XSRF token. In one aspect—XSRF encoding is performed for a set of URLs according to a configuration and then a token validation is performed for incoming requests to protected resources. In another aspect—XSRF token leakage via the referrer header to external URLs is prevented.

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. haemolytica 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.
