Intra-nasal inoculation of American bison (Bison bison) with ovine herpesvirus-2 (OvHV-2) reliably reproduces malignant catarrhal fever.

Plains bison, the subspecies found in the United States, were saved from extinction primarily by 5 private ranchers and the survival of a small herd in what is now Yellowstone National Park. This bottleneck resulted in the present-day plains bison population being descended fro...

Hepatic lipidosis in pregnant captive American bison (Bison bison).

Hepatic lipidosis, a hallmark lesion of lipid mobilization disorders in ruminants, was noted in four 3-year-old, pregnant bison (Bison bison) after periods of anorexia that progressed to recumbency and death. The affected bison were part of a herd at the National Animal Disease Center (NADC) that was used for brucellosis vaccine research. Microscopically, the liver contained swollen hepatocytes...
