During 1990-2002, no known cases occurred in Greater Yellowstone Area livestock. Since then, 17 transmission events from wildlife to livestock have been investigated.

Brucellosis Transmission between Wildlife and Livestock in the Greater Yellowstone Ecosystem: Inferences from DNA Genotyping.
The wildlife of the Greater Yellowstone Ecosystem carries brucellosis, which was first introduced to the area by cattle in the 19th century. Brucellosis transmission between wildlife and livestock has been difficult to study due to challenges in culturing the causative agent, Brucella abortus . We examined B. abortus transmission between American bison ( Bison bison ), Rocky Mountain elk ( Cerv...
متن کاملBrucellosis in the Greater Yellowstone area: disease management at the wildlifeâ•fi livestock interface
Elk (Cervus elaphus) and bison (Bison bison) of the Greater Yellowstone area are the last known reservoir of bovine brucellosis (Brucella abortus) in the United States. Domestic cattle occasionally contract the disease while grazing in areas where infected wild ungulates have aborted their fetuses or have given birth. Cases of brucellosis in cattle trigger costly quarantine, testing, and cullin...

Recurrent spillover of Brucella abortus from wildlife reservoirs to domestic cattle in the Greater Yellowstone Area (GYA) has prevented the United States from completely eradicating bovine brucellosis. Risks to cattle are a function of the size and location of wildlife and livestock populations, the degree and nature of spatio-temporal interactions between the various hosts, the level of diseas...
متن کاملBrucellosis in Elk in the Greater Yellowstone Area
Brucellosis is a highly contagious bacterial disease of both animals and humans. Infection of the female reproductive tract may result in abortion. The most common route of transmission is thought to be oral as a result of licking or ingestion of infected fetuses, placentas, fetal fluids, or vaginal exudates. Such transmission can be exacerbated under conditions that artificially congregate inf...
