猪椎间盘炎

Can J Comp Med. 1980 Apr;44(2):121-8.

Gross and microscopic lesions of discospondylitis in swine are described. Gross lesions were characterized by areas of destruction and cavitation involving intervertebral discs and adjacent structures. Microscopically, acute lesions had hemorrhage and necrosis with infiltration of granulocytes and mononuclear cells. In chronic cases intradiscal structures were replaced by vascular connective tissue which contained plasma cells and lymphocytes. These lesions were most frequently associated with chronic erysipelas polyarthritis.

描述了猪椎间盘炎的大体和微观病变。大体病变的特征是椎间盘和相邻结构出现破坏和空洞区域。微观上，急性病变有出血和坏死，并伴有粒细胞和单核细胞浸润。在慢性病例中，椎间盘内结构被含有浆细胞和淋巴细胞的血管结缔组织所取代。这些病变最常与慢性猪丹毒多关节炎相关。
