ABSTRACT． A female false killer whale (Pseudorca crassidens), estimated to be more than 25-years-old, died from chronic purulent pneumonia in spite of antibiotic therapy. At the necropsy, Vibrio alginolyticus was isolated from all samples including the lungs. Histopathologic examination revealed that multiple abscesses containing gram-positive cocci were present in the lungs. A comparison of the total protein, fibrinogen, leukocytes and average monthly temperatures for 8 years revealed an increase in total protein, an increase in subsequent average monthly temperatures, and an increase in both fibrinogen and leukocytes. Three items without the total protein were changed similarly. Bacteremia was observed in 4 out of 13 blood bacterial cultures. Additionally, in 3 out of 4 bacteremia, leukocytes were more than 20,000 /μl.

要約　推定25歳以上の雌オキゴンドウが，慢性化膿性肺炎で死亡した．肺を含む検体よりVibrio alginolyticusを分離し，組織学的には肺にグラム陽性球菌を含む化膿巣を認めた．実施した血液検査で，総蛋白が早期に，次に月平均体温，最後にフィブリノーゲンと白血球数が増加し，総蛋白以外の項目は類似した傾向を示した．菌血症4回中3回（血液細菌培養検査13回実施）で，白血球数は20,000 /μl以上だった．
