Since it was first described in the early 1980s, psittacine beak and feather disease (PBFD) has become recognised as the dominant viral pathogen of psittacine birds in Australia. Our aim was to evaluate and review the effect of PBFD and its position as a key threatening process to Australian psittacine bird species. We review the origin/evolutionary pathways and potential threat of PBFD to endangered psittacine bird populations and captive-breeding flocks.
The most recent beak and feather disease virus (BFDV) phylogenetic analyses indicate that all endangered Australian psittacine bird species are susceptible to, and equally likely to be infected by, BFDV genotypes from a range of host psittacine species. Management of the disease in captive-breeding programs has relied on testing and culling, which has proven costly. The risk of PBFD should be considered very carefully by management teams contemplating the establishment of captive-breeding flocks for endangered species. Alternative disease prevention tools, including vaccination, which are increasingly being used in wildlife health, should be considered more seriously for managing and preventing PBFD in captive flocks of critically endangered species.
自20世纪80年代初首次被描述以来，鹦鹉喙羽病（PBFD）已成为澳大利亚鹦鹉类鸟类中主要的病毒病原体。我们的目的是评估和审查PBFD的影响及其作为澳大利亚鹦鹉类鸟类关键威胁过程的地位。我们回顾了PBFD的起源/进化途径以及对濒危鹦鹉类鸟类种群和圈养繁殖群体的潜在威胁。
最新的喙羽病病毒（BFDV）系统发育分析表明，所有澳大利亚濒危鹦鹉类鸟类物种都易感染来自一系列宿主鹦鹉物种的BFDV基因型，并且感染可能性相同。圈养繁殖项目中的疾病管理依赖于检测和扑杀，事实证明这成本高昂。对于考虑为濒危物种建立圈养繁殖群体的管理团队而言，应极其慎重地考虑PBFD的风险。在野生动物健康领域越来越多地使用的包括疫苗接种在内的替代疾病预防工具，应更严肃地考虑用于管理和预防极度濒危物种圈养群体中的PBFD。
