Abstract: The present invention provides attenuated P. multocida strains that elicit an immune response in animal P. multocida, compositions comprising said strains, methods of vaccination against P. multocida, and kits for use with such methods and compositions. The invention further provides novel, genetically-engineered mutations in P. multocida hyaD and nanPU genes, which are useful in the production of novel attenuated P. multocida bacterial strains.

Abstract: The present invention provides attenuated M. haemolitica strains that elicit an immune response in animal against M. haemolitica, compositions comprising said strains, methods of vaccination against M. haemolitica, and kits for use with such methods and compositions. The invention further provides multi-valent vaccines, which provide protective immunity when administered in an effective amount to animals susceptible to “shipping fever” or bovine respiratory disease.

Abstract: The present invention is a Haemophilus parasuis vaccine against serovar type 4 capable of triggering a protective immune response when administered to pigs as a killed vaccine. The present invention is also a method for vaccinating swine against Haemophilus parasuis infection, serovar type 4, by a) clonally propagating one or more cells which are capable of triggering an immune response against Haemophilus parasuis infection, serovar type 4, that protects the pig against Haemophilus parasuis infection, and b) combining an immunologically effective amount of the cells with a veterinarily acceptable carrier in a form suitable for administration as a vaccine to the pig, and c) administering as a killed vaccine. The cell culture is from a pathogenic parent strain.
