Abstract

Among the 308 breeding pigs imported via airway from Canada, 15 pigs died from the respiratory disease. Three of the carcases were examined by pathological and bacteriological means. In the lungs of the necropsied cases there was a lobar pleuropneumonia characterized by parenchymal hepatization, carnification and extensive adhesion between the thoracic organs due to fibrinous pleural thickening. Histologically the affected lungs had lesions of thrombosis and coalesced area of necrosis delineated by packed macrophages. A strain of Haemophilus Pleuropneumoniae was isolated from the affected lungs. The isolate was serologically identified as serotype 5.
