Abstract: Vaccines against facultative intracellular pathogens are disclosed. A host is vaccinated with non-viable but metabolically active agents. The non-viable agents produce immunogenic components that elicit protective host immune responses, with minimal likelihood of host infection by the vaccine agent. Living agents, either attenuated or virulent, are exposed to a dose of gamma irradiation (or other strong mutagen) that is sufficient to limit or prevent the replication of the agents within the host, but that is insufficient to stop the metabolic activities of the agent. In vitro exposure of a microbial agent to the damaging effects of gamma irradiation or of another strong mutagen induces certain stress responses in the infectious agent. These stress responses are similar to the stress responses that the virulent agent would produce within the tissues of the host.

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.
