摘　　要：猪病的传播和流行一直是制约我国生猪养殖业发展的主要因素,特别是近年来猪病流行情况的日益复杂,非洲猪瘟、猪圆环病毒3型(Porcine Circovirus Type 3,PCV3)等多种新发疫病的不断出现,严重制约了我国生猪产业的发展,对生猪产业造成严重打击,同时也加速了我国猪场转型升级的步伐,对现代化猪场的生物安全和饲养管理提出了更高的要求。PCV3在2016年国内猪场发生至今,已传播扩散至我国多省的不同地区,成为严重威胁我国养猪业的一种新发疫病,PCV3感染导致猪群健康受损的同时,也大大增加了其他病原微生物感染的风险,且目前暂无有效疫苗对PCV3进行防控,给猪场造成了严重经济损失。本文对PCV3病原学特征、流行病学特点、临床症状和防控措施等方面进行简单综述,以期为预防PCV3的流行传播和基础研究提供参考。Pig disease has always been the main factor restricting the development of pig breeding industry in China,especially the in creasingly complex epidemic situation of pig disease in recent years.The continuous emergence of African classical swine fever,porcine circovirus type 3(PCV3)and other new diseases has not only seriously restricted the development of pig and animal husbandry in China,but also caused a serious blow.At the same time,it also accelerated the pace of transformation and upgrading of pig farms in China,and put forward higher requirements for biological safety and feeding management of modern pig farms.Since the outbreak of PCV3 in domestic pig farms in 2016,it has spread to many provinces and regions in China,becoming a new epidemic disease seriously threatening China's pig industry.PCV3 infection not only damaged the health of pigs,but also greatly increased the risk of infection of other pathogenic microorganisms.At present,there is no effective vaccine to prevent and control PCV3,causing serious economic losses to pig farms.This paper briefly summarized the etiological characteristics,epidemiological characteristics,clinical symptoms and prevention and control measures of PCV3,so as to provide reference for the prevention of epidemic transmission and basic research of PCV3.
