摘要
猪血凝性脑脊髓炎（PHE）是由血凝性脑脊髓炎病毒（HEV）感染引起猪的一种急性传染病,主要侵害1周龄~3周龄的哺乳仔猪。感染仔猪以呕吐、衰竭和神经症状为特征,病死率很高。血凝性脑脊髓炎病毒具有嗜神经性,主要从感染部位经外周神经向中枢神经系统传播,引起中枢神经系统损伤,从而造成非化脓性脑炎的病变。论文主要对猪血凝性脑脊髓炎的病原、临床症状和病理变化、致病机制、潜在危害及防治等方面进行综述。
Porcine hemagglutinating encephalomyelitis is an acute infectious disease caused by hemagglutinating encephalomyelitis virus（HEV）infection,and mainly infracts 1-3week old piglets.It causes encephalomyelitis,vomiting and wasting disease in suckling piglets.The mortality of HEV-infected piglets is very high.The hemagglutinating encephalomyelitis virus has the characteristics of neurotropism and mainly transmits from the infection site through the peripheral nerve to the central nervous system,causes the central nervous system damage,thus causes the pathological lesions of non purulent encephalitis.The pathogen,clinical symptoms,pathollgical lesions,potential hazards and prevention measures of porcine hemagglutinating encephalomyelitis were reviewed.
