摘　　要：对江苏省某三黄鸡鸡场饲养的60日龄育成鸡发生的慢性鸡白痢沙门菌感染进行了系统的病理学观察。剖检所见以心脏、气管、肺脏、肌胃出现大小不等的白色坏死结节,肝脏、脾脏肿大并形成白色坏死区为特征。病理组织学变化主要为各脏器的炎症如气管炎、肺炎、肝炎、脾炎、肾炎、盲肠炎、心肌炎,主要特征性变化为心肌和肌胃由大量组织细胞浸润取代肌肉纤维,从而形成肉眼可见的白色结节,而其他脏器的坏死结节或坏死灶则主要由坏死的组织、渗出的纤维素、嗜异性白细胞、单核细胞和淋巴细胞构成。从上述病例的肝脏病灶中分离到了鸡白痢沙门菌,为鸡白痢慢性感染的病理学诊断和鉴别诊断提供了依据。Five thousands of SanHuang broilers at the age of 60 days in Zhenjiang city were diagnosed as avian chonic Salmonellosis pullorum infection by bacteria isolation, virus isolation and parasitological inspection. Clinical signs in chickens include anorexia, diarrhoead, dehydration, weakness, respiratory sign and low mortality. Gross lesions included white nodules in trachea, lungs, heart and gizzard, enlarged liver , spleen and kidneys can be seen with white loci. Microscopic lesions include hepatitis, splenitis, typhlitis, myocarditis, pneumonia, nephoritis,most characteristic microscopic lesions was the infiltration of massive numbers of histiocytic type ceils arranged in solid sheets, which forming nodules that protruded from the surface of heart and gizzard,other white loci consisted of necrotic debris ,exudated fibrin ,lymphocytea, heterophUs and few plasma ceils. Salmonella pullorum was isolated from the livers, these results gave some awards to the pathological diagnosis and differential diagnosis of chronic pullorum disease in chickens.
