我们应用了深入的系统发育和系统地理分析。我们重建了AvCoV的进化历史。我们发现，在本研究中采样的AvCoV表现出很高的进化速度。我们已经推断出不同鸟类中AvCoV人口统计学种群的增加。评估的鸟类可能是负责传播avcov的潜在新宿主。禽流感冠状病毒（AvCoVs）的进化和种群动态仍未得到充分研究。本研究通过深入的系统发育和贝叶斯系统地理研究，探讨了野生和合群鸟类中检测到的avcov的进化动态。采用分子分析方法对从42种312只野生鸟类中采集的500份样本进行了分析，其中包括气管和肛肠拭子。22种鸟类共65份（13%）AvCoV阳性。分子进化分析显示，从巴西采集的样本序列与GenBank数据库中储存的AvCoV S1基因序列不存在聚类。贝叶斯框架分析估计，来自瑞典（1999年）的AvCoV毒株是本研究中检测到的AvCoV的最近共同祖先。此外，分析推断AvCoV在不同野生和共生鸟类物种中的动态人口统计学种群增加，这表明鸟类可能是负责传播该病毒的潜在新宿主。
We have applied in-depth phylogenetic and phylogeographic analyses. We have reconstructed the AvCoV evolutionary history. We have revealed that the AvCoV sampled in this study exhibits a high evolutionary rate. We have inferred an increase in the AvCoV demographic population in different bird species. The birds assessed may be potential new hosts responsible for spreading the AvCoVs. The evolution and population dynamics of avian coronaviruses (AvCoVs) remain underexplored. In the present study, in-depth phylogenetic and Bayesian phylogeographic studies were conducted to investigate the evolutionary dynamics of AvCoVs detected in wild and synanthropic birds. A total of 500 samples, including tracheal and cloacal swabs collected from 312 wild birds belonging to 42 species, were analysed using molecular assays. A total of 65 samples (13%) from 22 bird species were positive for AvCoV. Molecular evolution analyses revealed that the sequences from samples collected in Brazil did not cluster with any of the AvCoV S1 gene sequences deposited in the GenBank database. Bayesian framework analysis estimated an AvCoV strain from Sweden (1999) as the most recent common ancestor of the AvCoVs detected in this study. Furthermore, the analysis inferred an increase in the AvCoV dynamic demographic population in different wild and synanthropic bird species, suggesting that birds may be potential new hosts responsible for spreading this virus.
