This study was performed to clarify the clinical signs of macroscopical lesions of pigs naturally infected with hog cholera. There was clinical and macroscopical observation on the natural cases of hog cholera and experimental cases inoculated with ALD virus and isolated virus strains. In the clinical inspection of the natural cases, diarrhea (73.1%), blotching of ear (50.0), conjunctivitis (32.7%) and dyspnea (30.8%) were observed. Dyspnea, constipation and erythema of skin were observed mainly in the experimental cases, however, staggering and conjunctivitis in pigs infected with ALD virus were found and convulsion and hemorrhage of skin of pigs infected with isolated virus were seen, respectively. The gross lesions of natural cases were hemorrhage of lymph node (82.5%), pneumonia (55.0%), gastritis and hemorrhage (52.5%), cardial hemorrhage (40.0%) and renal petechiation (37.5%), while in the experimental cases, hemorrhage of lymph node, pneumonia, gastritis and hemorrhage, enteritis and hemorrhage of large intestine and splenic infarction were seen mainly
