摘　　要：小反刍兽疫是危害山羊和绵羊及野生小反刍兽的一种急性或亚急性、接触性、高致死性传染病。本病在世界范围内的流行已有70余年的历史,流行范围不断扩大。该病的病原是小反刍兽疫病毒(PPRV),与牛瘟病毒抗原性和亲缘关系密切相关。山羊和绵羊是本病的自然宿主,多种小反刍兽也可感染发病。感染和发病羊是传染源,健康羊与发病羊直接接触通过呼吸道感染,间接接触也能感染,本病在多雨季节和干燥寒冷季节多发。病羊表现出发热、眼、口、鼻分泌物增多、严重腹泻、糜烂性口炎等症状。剖检发现口腔坏死、糜烂,鼻黏膜坏死,支气管肺炎和肺尖肺炎,消化道出血,直肠的病变呈斑马状,脾肿大、坏死。通过强化外引羊只的监管和监测,加强饲养管理,必要时进行疫苗免疫是防止该病发生的有效技术措施。Peste des Petits Ruminants（PPR） is a kind of infection disease contained much charac-teristics, such as acute, touching and hypso-fatal and so on.
