目前,2019新型冠状病毒(SARS-CoV-2)在我国各地暴发和流行,但其主要来源尚不清楚。曾有报道称该病毒来源于野生动物,如蝙蝠。而有关SARS-CoV-2在我国北方地区人工养殖的水貂、狐狸和貉等毛皮动物中的溯源性研究尚未见报道。本研究收集2016～2019年吉林、黑龙江、辽宁、河北和山东5个省份14个地区的不明原因死亡的水貂、狐狸和貉的625份组织样品,以及2019年8～12月在吉林省采集的水貂、狐和貉的150份粪便样品,通过WHO推荐的Real-time RT-PCR检测方法对上述组织及粪便样品中SARS-CoV-2进行检测。结果显示,上述775份样品中SARS-CoV-2核酸检测结果均为阴性。
Abstract：In December 2019,an outbreak of a respiratory illness took place in Wuhan,Hubei Province,China,and spread throughout China and other countries. A β genus coronavirus,SARS-CoV-2 was isolated and identified as a cause of the outbreak. Currently,the main infectious sources(host)of SARS-CoV-2 have not been identified. It has been reported that SARS-CoV-2 was possibly originated from wild animals,for example,bats. However,there are no reports on the traceability of SARS-CoV-2 to fur animals,such as minks,foxes and raccoon dogs,which are widely farmed in Northern China. Therefore,it is necessary to investigate the epidemiology of SARS-CoV-2 in fur animals. In this study,we detected SARS-CoV-2 in 625 tissue specimens collected from farmed minks,foxes and raccoon dogs of unknown death cases in 14 regions of China from 2016 to 2019 and 150 fecal samples collected from farmed minks,foxes and raccoon dogs in Jilin Province,China from August to December in 2019 using the Real-time RT-PCR method recommended by WHO. The results showed that SARS-CoV-2 was not detected in all the 775 samples.
