Abstract
The present invention provides novel attenuated Pasteurella multocida strains that may be used, in live or killed form, to formulate vaccines that are highly protective against P. multocida infection in bovines, other mammals, and in birds. The present invention also identifies the combination of nanP and hyaC gene mutations as key to the provision of such vaccines. When appropriately formulated, antigenic material of numerous other bovine pathogens may be combined with the live attenuated Pasteurella multocida strains, to make effective combination vaccines.
