摘要
实验用三周龄健康哺乳仔猪18头,随机分为三组,以三种接种途径(脑内注射、滴鼻和肌肉注射)、不同剂量感染三株伪狂犬病毒株(PrV-S、Pry-闽A和PrV-Shope)。发病仔猪于体温升高至41～12℃后反复出现神经症状。尸体剖检除脑膜充血水肿外,一些病例肺和肝出现小的坏死灶。病理组织学变化主要为淋巴细胞性脑膜脑脊髓炎和神经节的神经元广泛变性坏死。在大脑、神经节、扁桃体、肺和淋巴结发现核内包涵体。
Eighteen three week piglets without PrV antibody were divided into three groups,infected with one of three strains of pseudorabies virus by various routes of inoculation respectively. The microscopical lessions were non-suppurative meningoencephalomyelitis and ganglionitis. Necrosis and inflammation were found in the ganglions and a number of internal organs. Intranuclear inclusions were present in the cerebrum, ganglions, lungs, tonsils and lymph nodes.The pathological differences among various strains or inoculating routes were discussed
