Interpretive Summary: Brucella abortus is a disease that causes abortion and associated economic losses in infected cattle herds. The infection of bison and elk with Brucella abortus in Yellowstone National Park pose a risk to the completion of the Brucellosis Eradication Program for cattle. Development of a protective vaccine for bison would be beneficial in resolving the controversy caused by brucellosis in bison. As use of a vaccine in bison might lead to environmental exposure of bears, these studies evaluated the safety of a potential vaccine for bison, Brucella abortus strain RB51, in bears. Our data suggests that exposure of black bears to strain RB51 causes no clinical illness or effects on reproduction. This data will be of benefit to the National Park Service and the states of Montana, Wyoming, and Idaho in their efforts to resolve the brucellosis problem in the Yellowstone National Park bison and elk. Development of an environmentally safe brucellosis vaccine for bison reduce the risk of transmission of brucellosis from bison to livestock, which will facilitate the completion of the Brucellosis Eradication Program.
