摘　　要：猪环曲病毒在世界范围内广泛分布,猪群感染率高,在腹泻病例中检出率高,被认为是一种可能的猪腹泻病原。凸隆病毒的型间重组和抗原交叉反应,意味着猪环曲病毒存在人兽共患的风险。基于近年在我国部分地区因为仔猪腹泻导致了较大损失,本文介绍了猪环曲病毒发展历史,综述了该病毒基因组和蛋白特点、流行病学、实验室诊断等,以期为相关研究提供参考。Porcine Torovirus （PToV） is widely distributed in the world with high prevalence rate in swiner- y. Due to the high detection rate in diarrhea pigs, PToV is thought to be a potential pathogen of swine di- arrhea. In recent years, epidemic outbreaks of diarrhea with high morbidity and mortality in China have caused great economic losses. Intertypic recombination events and antigenic cross-reactivity among torovir- uses implies potential zoonotic transmission of PToV. The review represented the development history of PToV and made a brief summary of the features in genome and protein epidemiology and laboratory diag- nosis of the PToV, and so on.
