While single-stranded DNA (ssDNA) was once thought to be a relatively rare genomic
architecture for viruses, modern metagenomics sequencing has revealed circular ssDNA …

Background 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 …

Purpose. Beak and feather disease virus (BFDV) is a circovirus and the cause of psittacine
beak and feather disease (PBFD). This disease is characterized by feather and beak …

Emerging viral pathogens are a significant concern, with potential consequences for human,
animal and environmental health. Over the past several decades, many novel viruses have …

Psittacine beak and feather disease (PBFD), caused by Beak and feather disease virus
(BFDV), has spread rapidly around the world, raising concerns for threatened species …

Beak and feather disease virus (BFDV) is the dominant pathogen of wild Psittaciformes in
Australasia where it has been present for at least 10 million years. The richness of psittacine …

Beak and feather disease virus (BFDV), which causes psittacine beak and feather disease
(PBFD), is known to infect a wide range of bird species, with all members of the …

Pathogens pose a major risk to wild host populations, especially in the face of ongoing
biodiversity declines. Beak and feather disease virus (BFDV) can affect most if not all …

The presence of endogenous viral elements in host genomes hints towards much older host–
virus relationships than predicted by exogenous phylogenies, with highly mutable single …

Emerging diseases are acknowledged as a growing threat to wildlife, with the continued
identification of pathogenic and potentially pathogenic viruses in avian species resulting …
