引发鹦鹉喙羽症（PBFD）的病毒即喙羽症病毒（PBFDv或BFDV），是一种圆环病毒（环状病毒，circovirus）。 （实际上，能感染鸟类的圆环病毒除了PBFDv还有鸽圆环病毒、鸡贫血病毒。

Beak and feather disease virus (BFDV) is a globally distributed pathogen of one of the most threatened bird orders world-wide, the Psittaciformes (parrots, cockatoos, lorikeets) [5]. It has recently also been found in non-psittacine bird species, showing the capacity for spill-over infections to taxa outside the Psittaciformes [14 – 16].

Psittacine beak and feather disease (PBFD) is a viral disease affecting all Old World and New World parrots. The causative virus—Beak and feather disease virus (BFDV)—belongs to the taxonomic genus Circovirus, family Circoviridae.

2020年7月1日 · Beak and feather disease virus (BFDV) can affect most if not all members of one of the largest and most threatened bird orders world-wide, the Psittaciformes. Signs of disease can be severe and mortality rates high.

Psittacine beak and feather disease (PBFD) is one of the most common viral diseases in parrot species. The causative agent is among the smallest birds’ viruses (7-22 nm) and named beak and feather disease virus (BFDV). The virus is non-enveloped and icosahedral, and is composed of an ambisense, circular, non-segmented, single stranded DNA.

Beak and feather disease virus (BFDV) infects psittaciform birds (parrots). The virus seems to have originated in Australia where it continues to threaten wild parrot populations (Fig. 35.3). The virus is also found worldwide in captive parrots.

2022年2月18日 · We conducted a PCR screening for the beak and feather disease virus (BFDV) using samples collected during previous field studies (1993–2014) in five populations of parrots of the Southern Hemisphere: Eclectus parrots (Eclectus roratus) and Crimson rosellas (Platycercus elegans) from Australia, Burrowing parrots (Cyanoliseus patagonus) and ...

2017年9月11日 · Background: Beak and feather disease virus (BFDV) is an important disease causing agent affecting psittacines. BFDV is highly infectious and can present as acute, chronic or subclinical disease. The virus causes immunodeficiency and is …

Psittacine beak and feather disease virus (PBFDV) and budgerigar fledgling disease virus (BFDV) are significant avian pathogens that threaten both captive and wild birds, particularly parrots, which are common hosts. This study involved sampling and ...
