Abstract

Authors observed an outbreak of porcine pleuropneumonia at a piggery in Gyeongbug, Korea, which were diagnosed on the ground of clinical and pathological findings with the following results. 1. One hundred and forty weanlings out of 200 ones died suddenly without noticiable signs during the period of 15 days. All of the dead pigs showed formy, blood-tinged discharge from the nose and mouth. 2. Main clinical findings observed from 60 alive pigs from group consisted of fever, cyanosis severe degree of dyspnea and pleuritic friction rub. 3. On hematological observation for typical 5 cases leukocytes showed marked degenerative left shift with leukopenia (10500-13070/cmm), neutropenia (7-13%) and increase in the number of band neutrophils (6-27%). 4. The most prominent and constant pathological changes observed at necropsy for dead or alive pigs consisted of fibrinous pleurisy with partial adhesion, overlying of the pulmonary surface with fibrinous menbrane and necrotic pneumonic lesions with marked edema and congestion of lung parenchyma. 5. From these results the outbreak was considered to be typical porcine pleuropneumonia, although no bacteriological isolation was attempted.
