Malignant Catarrhal Fever (MCF) is a viral disease caused by a group of gammaherpesviruses. It primarily affects cattle, deer, bison, and other ruminants, often with severe outcomes. Adding to the severity, many of the carrier species don't show symptoms of the disease. In this episode, Dr. Brandon Dominguez and Dr. Terry Hensley discuss testing options and disease details with Dr. Gabe Gomez, assistant agency director for pathology.
