Abstract

This study was taken to clarify the clinical signs and macroscopical lesions of pigs naturally infected with hog cholera. The clinical and macroscopical observation on the natural cases of hog cholera and experimental cases inoculated with ALD Virus and isolated virus strains were carried out. The results obtained are as follow; In clinical inspection of the natural cases, diarrhea (73.1%) blotching of ear (50.0%), staggering (42.3%), erythema of skin (40.0%), constipation (38.5%), 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%), enteritis and hemorrhage of large intestine (65.0%), splenic infarction (57.5%), pneumonia (55.0%), gastritis and hemorrhage (52.5%), cardiac 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 laryge intestine and splenic infarction were seen mainly.
