Dear Editor,rnThe emergence of COVID-19 since December 2019 has attracted great attention around the world and reminds the powerful pathogenic potential of viruses (Zhou et al.2020).The subfamily Orthocoronavirinae of the family Coronaviridae contains four genera Alphacoronavirus,Betacoronavirus,Gamrnacoronavirus,and Deltacoron-avirus,which are the largest group of positive-sense,non-segmented,single-stranded,enveloped RNA viruses (Woo et al.2012;Shi et al.2016).The genus Gammacoronavirus currently has five species (https://talk.ictvonline.org/tax onomy/),which are primarily spread through birds (Woo et al.2012).Infectious bronchitis virus (IBV) is the best-studied Gammacoronavirus,which can lead to economic losses to the global poultry industry by causing avian infectious bronchitis (a highly contagious viral respiratorydisease) (Jackwood and de Wit 2020).Turkey coronavirus(TCoV),also a member of Garnmacoronavirus,causes acute infectious diarrhea in domestic turkeys (Lin et al.2002).Recently,a novel species of genus Gammacoron-avirus was identified in a mass die-off of Canada and snow geese (Papineau et al.2019).
