Gross and histopathologic investigations were carried out on the viscera, the brain, and the spinal cord of sheep spontaneously infected with listeriosis. It was found that with the protracted course of the disease the gross lesions were found in the various sections of the spinal cord too. Besides, with the chronic course of the nervous form of listeriosis in sheep the morphologic lesions consist of purulent necrotic meningoencephalitis and of myelitis. Histopathologically, myelitis is manifested by lymphohistiocytic infiltrations around the vessels and diffuse or focal infiltration of neutrophile leukocytes.
对自然感染李氏杆菌病的绵羊的内脏、脑和脊髓进行了大体和组织病理学检查。结果发现，随着病程的延长，脊髓的各个节段也出现了大体病变。此外，在绵羊李氏杆菌病神经型的慢性病程中，形态学病变包括化脓性坏死性脑膜脑炎和脊髓炎。组织病理学上，脊髓炎表现为血管周围的淋巴细胞组织细胞浸润以及中性粒细胞的弥漫性或局灶性浸润。
