OBJECTIVE
To discover beak and feather disease virus (BFDV) genotypes in Australian parrots that might threaten vulnerable and endangered psittacine bird species.
METHODS
Phylogenetic analyses of new DNA sequence data from Australian birds including the Rep gene (n = 55) and nine whole genomes, were compared with all available published BFDV genomes to assess host- and geographically-based divergence as well as probable host-switch events.
RESULTS
Strong support for flexible host-switching and recombination was detected, indicating active cross-species transmission in various subpopulations.
CONCLUSION
The data suggested that all endangered Australian psittacine bird species are equally likely to be infected by BFDV genotypes from any other close or distantly related host reservoir species.
目的
在澳大利亚鹦鹉中发现可能威胁易危和濒危鹦鹉鸟类物种的喙羽病病毒（BFDV）基因型。
方法
对来自澳大利亚鸟类的新DNA序列数据进行系统发育分析，包括Rep基因（n = 55）和九个全基因组，并与所有已发表的BFDV基因组进行比较，以评估基于宿主和地理的差异以及可能的宿主转换事件。
结果
检测到对灵活宿主转换和重组的有力支持，表明在各种亚种群中存在活跃的跨物种传播。
结论
数据表明，所有濒危的澳大利亚鹦鹉鸟类物种同样有可能被来自任何其他近缘或远缘宿主库物种的BFDV基因型感染。
