Psittacine beak and feather disease (PBFD) is one of the most important viral diseases affecting parrot species worldwide. Outbreaks of PBFD have been reported in wild endemic and endangered South African Cape Parrots (Poicephalus robustus), most recently in 2008. A previous study of wild Cape Parrots in the Eastern Cape region of South Africa in 2010-11 found 34/49 birds positive for beak and feather disease virus (BFDV), the causative agent of PBFD, showing that the outbreak was still ongoing. The present study (2015-16) screened 30 blood samples from the same Cape Parrot population for BFDV infection by PCR: all parrots were found to be BFDV DNA-negative, which showed both that BFDV infection in the region has declined and that the parrot population has recovered. Our data contribute to the important negative data set which permits monitoring the progress of BFDV infections in wild Psittaciformes. We recommend a PCR method with universal BFDV primers as a quick, easy, and consistent diagnostic test for BFDV detection.
鹦鹉喙羽病（PBFD）是影响全球鹦鹉物种的最重要的病毒性疾病之一。在南非野生的地方特有种和濒危的海角鹦鹉（Poicephalus robustus）中已报告有PBFD疫情爆发，最近一次是在2008年。2010 - 2011年对南非东开普地区野生海角鹦鹉的一项先前研究发现，49只鸟中有34只喙羽病病毒（BFDV）呈阳性，BFDV是PBFD的病原体，这表明疫情仍在持续。本研究（2015 - 2016年）通过PCR对来自同一海角鹦鹉种群的30份血液样本进行了BFDV感染筛查：所有鹦鹉均被发现BFDV DNA呈阴性，这既表明该地区的BFDV感染有所下降，也表明鹦鹉种群已经恢复。我们的数据为重要的阴性数据集做出了贡献，该数据集有助于监测野生鹦鹉形目动物中BFDV感染的进展情况。我们推荐使用带有通用BFDV引物的PCR方法作为一种快速、简便且一致的BFDV检测诊断测试。
