摘　　要：猪圆环病毒(PCV)是圆环病毒科圆环病毒属的单股环状闭合DNA病毒,是引起猪圆环病毒相关疾病(PCVAD)的主要病原,目前包括4个基因型:PCV1、PCV2、PCV3和PCV4。其中,PCV3是近年来新发的一种严重危害养猪业的基因型,已经在全球范围呈现广泛流行趋势,引起了国内外学者的广泛关注。本文主要从病原学、流行病学、临床症状、致病机理、免疫反应和诊断方法对PCV3近年来研究情况进行了综述,为PCV3后期的各方面研究提供参考。Porcine circovirus(PCV)is a single-stranded,closed-circular DNA virus belonging to the Circovirus genus within the Circoviridae family.It is the primary pathogen responsible for porcine circovirus-associated diseases(PCVAD).Currently,there are four recognized genotypes,including PCV1,PCV2,PCV3,and PCV4.Among them,PCV3 is a newly emerged genotype that poses a significant threat to the swine industry,it has shown a global prevalence trend in recent years,and garnered widespread attention from researchers worldwide.This review provides an overview of recent research on PCV3,covering its etiology,epidemiology,clinical symptoms,pathogenesis,immune responses,and diagnostic methods.It serves as a reference for future studies on various aspects of PCV3.
