Beak and feather disease virus (BFDV), the causative agent of psittacine beak and feather disease (PBFD) infects psittaciformes worldwide. We provide an annotated sequence record of three full-length unique genomes of BFDV isolates from budgerigars (Melopsittacus undulatus) from a breeding farm in South Africa. The isolates share >99% nucleotide sequence identity with each other and approximately 96% nucleotide sequence identity to two recent isolates (Melopsittacus undulatus) from Thailand but only between 91.6 and 86.6% identity with all other full-length BFDV sequences. Maximum-likelihood analysis and recombination analysis suggest that the South African budgerigar BFDV isolates are unique to budgerigars, are non-recombinant in origin, and represent a new genotype of BFDV.
喙羽病病毒（BFDV）是导致鹦鹉喙羽病（PBFD）的病原体，感染全世界的凤头鹦鹉目鸟类。我们提供了来自南非繁殖场的虎皮鹦鹉（Melopsittacus undulatus）的三个全长独特 BFDV 分离株的注释序列记录。这些分离株彼此之间共享>99%的核苷酸序列同一性，与来自泰国的两个最近的分离株（虎皮鹦鹉）大约有 96%的核苷酸序列同一性，但与所有其他全长 BFDV 序列的同一性仅在 91.6%至 86.6%之间。最大似然分析和重组分析表明，南非虎皮鹦鹉 BFDV 分离株是虎皮鹦鹉特有的，起源是非重组的，代表了 BFDV 的一个新基因型。
