摘　　要：猪圆环病毒相关疾病(PCVAD)已成为世界范围内影响养猪业发展的重要疾病。由猪圆环病毒2型(PCV-2)引发的肠炎是PCVAD的症状之一,临床表现为生长仔猪腹泻、生长发育迟缓或体重减轻;在淋巴组织和肠组织中可检测到大量的PCV-2病原,并出现特征性组织学病变。试验证实,PCV-2单独感染或与其他病原混合感染可引发肠炎,经口服途径攻毒感染是引发PCV-2相关肠炎疾病的一种重要感染途径。因此,PCV-2是生长仔猪肠道疾病的一种致病因子,应予以足够重视。论文对PCV-2相关肠炎在临床表现、组织病理学特征、多病原混合感染对其影响、临床诊断以及防控措施等方面的研究进展进行综述,以期对PCV-2相关肠炎疾病的深入研究提供参考。Porcine circovirus-associated disease （PCVAD） has emerged as an economically important pig dis- ease globally. Porcine circovirus type 2 （PCV-2）-associated enteritis is one of PCVAD, and its clinical signs are diarrhea, growth retardation or weight loss in growing pigs. Large amounts of PCV-2 specific antigens could be detected in intestines and lymohoid tissues, meanwhile characteristic microscopic lesions could be observed. It is reported that under experimental conditions,PCV-2 could induce enteritis independently or together with other pathogens and oral challenge is an important infection route for PCV-2-associated en- teritis. PCV-2 is also a causative agent of enteric disorders in growing pigs,which needs more attention. In this article,the recent achievements in clinical signs, histopathological features, impact of multi-pathogen co-infection, diagnosis and control measures of PCV-2-associated enteritis were reviewed in order to serve as important references for researchers in this field.
