A Japanese Black calf became dehydrated on the first day of life and died on the third day. Gross examination revealed a large amount of yellowish-brown serous fluid in the abdominal cavity and whitish-yellow fibrin in the serosa of the abdominal organs. Patchy red spots were observed throughout the peritoneum, and the outer membrane of the umbilical arteries was dark red. Bacteriologically, Mannheimia haemolytica serotype 2 was isolated from the umbilical arteries and vein, liver, and kidney. Histopathology revealed inflammation with M. haemolytica serotype 2 in the outer membrane of the umbilical arteries and in the serosa of the bladder and intestinal tract. This is the first case of bovine peritonitis with histopathologic and immunohistochemical identification of M. haemolytica.
一头日本黑牛犊在出生第一天出现脱水，并于第三天死亡。大体检查发现腹腔内有大量黄棕色浆液性液体，腹部器官浆膜有灰白色黄色纤维蛋白。整个腹膜可见散在的红色斑点，脐动脉外膜呈暗红色。细菌学检查从脐动脉和静脉、肝脏及肾脏中分离出溶血性曼氏杆菌血清型2。组织病理学显示脐动脉外膜、膀胱和肠道浆膜有溶血性曼氏杆菌血清型2引起的炎症。这是首例经组织病理学和免疫组织化学鉴定为溶血性曼氏杆菌引起的牛腹膜炎病例。
