Abstract: This paper reports the pathological lesions about the fowl cholera in pheasants caused by pasteurella multocida. At necropsy, the changes mainly appeared in liver, spleen, lungs and duodenum. There were many focal necroses on the surfaces of liver and spleen which were swollen. Lungs showed congestion and edema. The duodenal mucosa was swollen, hyperemic and hemorrhagic. Histopathologically, the lesions were characterized by acute paranchymatous hepatitis, acute necrotic splenitis, hemorrhagic and catarrhal duodenitis, the congestion and edema of lungs, the degeneration of renal tubules and focal necroses in kidoeys and the hyperemia and cellular degcneration in heart. There were a lot of bacteria and bacterial emboluses in the above lesion organs. Results demonstrated that the fowl cholera in pheasants could be diagnosed according to the above mentioned pathological changes. Comparison of the pathological lesions of fowl cholera between pheasant and chicken and pathogensis was also discussed in the paper.
