Abstract
The present invention provides novel attenuatedstrains that may be used, in live or killed form, to formulate vaccines that are highly protective againstinfection 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 attenuatedstrains, to make effective combination vaccines.
