七彩山鸡霍乱的病理形态学观察

本文对多杀性巴氏杆菌引起的山鸡霍乱自然病例作了系统的病理形态学观察。眼观病变主要表现为肝脾肿大、表面布有多量灰白色或灰黄色坏死点，肺脏郁血水肿，十二指肠粘膜肿胀充血出血；镜下变化呈急性实质性肝炎、急性坏死性脾炎、出血性和卡他性十二指肠炎、肺脏郁血众肿、肾脏变性与灶性凝固性坏死以及心脏充血和心肌纤维颗粒变性，并在病变器官组织中出现大量细菌或细菌性栓子。上述病变可作为诊断山鸡霍乱的病理学依据。文中还探讨了发病机理，并与家禽霍乱的病变特点作了比较。

MORPHOPATHOLOGICAL OBSERVATION OF FOWL CHOLERA IN SEVEN-COLORED PHEASANTS

This paper reports the pathological lesions about the fowl cholerain pheasants caused by pasteurella multocida. At necropsyt the changes mainlyappeared in liver, spleen, lungs and duodenum. There were many focal necroses onthe surfaces of liver and spleen which were swollen. Lungs showed congestion andedema. The duodenal mucosa was swollen, hyperemic and hemorrhagic. Histopatholo-gically, the lesions were characterized by acute paranchymatous hepatitis, acutenecrotic splenitis, hemorrhagic and catarrhal duodenitis, the congestion and edemaof lungs, the degeneration of renal tubules and focal necroses in kidoeys and thehyyeremia and cellular degcneration in heart. There were a lot of bacteria andbacterial emboluses in the above lesion organs. Results demonstrated that thefowl cholera in pheasants could be diagnosed according to the above mentionedpatbological clanges. Comparison of the pathological lesions of fowl cholerabetween pheasant and chicken and pathogensis was also discussed in the paper.
