CORYNEBACTERIUM PSEUDOTUBERCULOSIS AND COPPER DEFICIENCY IN A MALE ROCKY MOUNTAIN BIGHORN SHEEP (OVIS CANADENSIS CANADENSIS) IN UTAH, USA

ABSTRACT:  In 2015, an emaciated Rocky Mountain bighorn (Ovis canadensis) ram was submitted to the Utah Veterinary Diagnostic Laboratory for necropsy. There were numerous thick-walled abscesses subcutaneously and internally, and Corynebacterium pseudotuberculosis was isolated in pure culture. In addition, the ram was severely copper deficient, with a liver copper concentration of 1.6 mg/kg.
