Hog Cholera presents as a severe, systemic infection that damages blood vessels, leading to multiple organ lesions alongside fever and depressed appetite. The best description combines the general signs of an acute viral illness with specific gross lesions that are classically associated with Classical Swine Fever. The combination of splenic infarcts, tonsillar necrosis, and kidneys described as turkey-egg kidneys, together with fever, depression, and anorexia, captures both the widespread vascular damage and the characteristic organ changes seen in acute disease. Splenic infarcts reflect vascular occlusion, tonsillar necrosis shows mucosal and lymphoid involvement from viral replication in vessels, and the turkey-egg kidney appearance indicates renal infarcts and necrosis. While ocular or nasal discharge with fever can occur in various swine diseases, and coughing alone is not typical for Hog Cholera, and skin redness without fever is not consistent with the acute systemic picture, the combination described here is the most distinctive for Classical Swine Fever.
