猪δ冠状病毒研究进展 Research Progress on Porcine Deltacoronavirus

猪δ冠状病毒是近年发现的一种新型猪肠道病冠状病毒，可引起猪急性腹泻和新生仔猪死亡。目前没有有效的抗病毒治疗药物和疫苗。自从2014年初美国报道检出PDCoV以来，PDCoV快速蔓延至多个国家，具有全球流行的潜在趋势，引起了世界各国的极大关注及众多的调查研究。本文就PDCoV的病原学、流行病学、检测技术等方面的研究进展进行综述，为该病的进一步研究和有效防控提供依据。 Porcine deltacoronavirus (PDCoV) is an emerging swine enteropathogenic coronavirus that causes acute diarrhea and mortality in piglets. At present, there is no proven medication or vaccine for PDCoV. Since it was reported in the US in early 2014, PDCoV has spread to many countries and has the potential of global endemic. It has raised global public health concerns regarding the current sistution and its future evolution. Recent advances in studies on etiology, epidemiology and laboratory diagnosis about PDCoV were summarized in this paper to provide the guidance for its further research and prevention.
