Sheep-associated malignant catarrhal fever (MCF) is a sporadic viral disease of cattle and other ruminants that is due to ovine herpesvirus-2. It causes serious disease outbreaks of disease in high-value animals, particularly commercial bison, game farms and zoos. In collaboration with investigators at the Department of Microbiology at Washington State University (Drs. T Crawford and H Li), we have been examining the epidemiology of infection in cattle and sheep. Recently the research group successfully reproduced the disease using the natural route of infection (aerosol) for the first time in bison, sheep and cattle by aerosol inoculation. The goal is to develop a success control strategy using either natural resistance traits identified in bison, or a vaccine approach.
