马传染性贫血是一种遍布全球的病毒性传染病。病理变化自然死亡的病马或疾病过程中杀死的病马,其病变性质在很大程度上取决于疾病的临床类型和持继时间的久暂。换言之,由于病情反复恶化而死亡的慢性病例,其多种组织的病变比单纯急性型死亡者复杂的多。一般变化:急性型眼观主要有黄疸、水肿和出血。水肿最明显的部位是腹壁的真皮下层,心脏的底部,以及肾周围和腰下脂肪。在水肿部位或浆膜,特别是胸、腹膜,可见瘀点或瘀斑。实质器官肿大。亚急性型也可出现水肿和出血,但贫血,肝脏肿大和色素沉着,脾脏、淋巴结和肾脏肿大,以及骨髓增生等等则更为显著。慢性型迫杀的动物仅仅可能见到脾脏和骨髓肥大。 Infectious anemia is a viral infection that spreads throughout the world. The nature of the lesion depends on the clinical type of disease and the long duration of the disease, either as a result of a naturally occurring disease or as a kills killed during a disease.

General changes: acute type of eye mainly jaundice, edema and bleeding. The most prominent sites of edema are the hypodermis of the abdominal wall, the bottom of the heart, and the perirenal and subcutaneous fat. In the edema site or serosa, especially the chest, peritoneum, visible petechiae or ecchymosis. Physical organ enlargement. Subacute type may also appear edema and bleeding, but anemia, liver enlargement and pigmentation, spleen, lymph nodes and kidney enlargement, and myeloid hyperplasia and so on are more significant.
