Abstract:
... Psittacine beak and feather disease (PBFD), caused by beak and feather disease virus (BFDV) is a highly contagious disease in wild and captive psittacine populations and has an almost global presence. However, the BFDV infection in Saudi Arabia remains largely unknown. In the present study, we report the full genome sequence of BFDV strains from Saudi Arabia and its genetic diversity. The complete ...

... Beak and feather disease virus (BFDV) is an avian circovirus, and it has a single-stranded DNA genome. It causes a fatal disease in parrots called psittacine beak and feather disease (PBFD). After screening of samples collected from Taiwan using PCR, complete genome sequences of isolates from 21 samples from various species of parrot were obtained. The nucleotide sequences of the replication-assoc ...

Abstract:
... 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 ~96% nucleotid ...
