In December 2008, near Flaming Gorge Reservoir in northeastern Utah, a 2 ½-year-old male Rocky Mountain bighorn sheep (Ovis canadensis canadensis) was reported in poor body condition with bloody lesions covering the muzzle area. The sheep was euthanized, and samples were submitted to the Utah Veterinary Diagnostic Laboratory in Logan, Utah. The gross and microscopic lesions confirmed the diagnosis of contagious ecthyma (CE). This is the first documented report of CE in bighorn sheep from Utah.
