发布时间：2018-11-13 18:10
【摘要】：塞内卡病毒病是由微RNA病毒科的A型塞内卡病毒(Senecavirus A,SVA)引起的动物传染病,主要感染猪,不同年龄阶段的猪均易感,但不同毒株的致病力明显不同,引起的临床症状也不尽相同。早期的分离株多导致亚临床感染,近年来的分离株通常引起口蹄疫样的临床症状,病猪口鼻部、蹄部出现水疱、溃疡,新生仔猪死亡率显著增加。目前,该病主要流行于加拿大、巴西和美国等国家;2015年以来,我国广东和湖北两省某些猪场相继发生SVA疫情。为提高人们对该病的认识和重视,及早做好相关防控预案和检测技术储备,笔者从病原学、流行病学、临床症状与病理变化、检疫与诊断、防控措施等方面对取得的最新研究进展进行概述。
[Abstract]:Seneca virus disease is an animal infectious disease caused by Senecavirus Agna virus of the family RNA. It mainly infects pigs and pigs of different ages, but the pathogenicity of different strains is obviously different. The clinical symptoms are also different. The early isolates usually cause subclinical infection. In recent years, the isolates usually cause foot-and-mouth disease symptoms, blisters in the mouth, nose and hoof of pigs, ulcers, and mortality of newborn piglets. At present, the disease is mainly prevalent in Canada, Brazil and the United States. Since 2015, SVA outbreaks have occurred in some pig farms in Guangdong and Hubei provinces of China. In order to improve people's understanding and attention to the disease, and to make the relevant prevention and control plan and detection technology reserve as early as possible, the author from etiology, epidemiology, clinical symptoms and pathological changes, quarantine and diagnosis, The latest research progress in prevention and control measures is summarized.
