我们在水生野生鸟类中检测到新型禽流感冠状病毒的高流行率(12.5%)。对这些冠状病毒的系统发育分析表明，在鸟类中流行着多种伽马冠状病毒和斑冠状病毒。在本研究中，革冠状病毒主要存在于雀形目鸟类中，而斑冠状病毒可在环形目、斑冠状和雀形目鸟类中检测到。我们观察到，在鸭种之间存在频繁的伽马冠状病毒的种间传播。相比之下，三角洲冠状病毒可能具有更严格的宿主特异性。我们对这些禽类病毒和宿主线粒体DNA序列的分析也表明，一些但不是全部冠状病毒可能与同一目的鸟类共同进化。
We detected a high prevalence (12.5%) of novel avian coronaviruses in aquatic wild birds. Phylogenetic analyses of these coronaviruses suggest that there is a diversity of gammacoronaviruses and deltacoronaviruses circulating in birds. Gammacoronaviruses were found predominantly in Anseriformes birds, whereas deltacoronaviruses could be detected in Ciconiiformes, Pelecaniformes, and Anseriformes birds in this study. We observed that there are frequent interspecies transmissions of gammacoronaviruses between duck species. In contrast, deltacoronaviruses may have more stringent host specificities. Our analysis of these avian viral and host mitochondrial DNA sequences also suggests that some, but not all, coronaviruses may have coevolved with birds from the same order.
