Beak and feather disease virus; Psittacidae; coat proteins; disease reservoirs; endangered species; gene flow; genotype; hosts; pathogens; phylogeny
Abstract:
... The establishment of viral pathogens in new host environments following spillover events probably requires adaptive changes within both the new host and pathogen. After many generations, signals for ancient cross-species transmission may become lost and a strictly host-adapted phylogeny may mimic true co-divergence while the virus may retain an inherent ability to jump host species. The mechanisti ...

Abstract:
... Beak and feather disease virus (BFDV) belongs to the family Circoviridae. A rolling-circle replication strategy based on a replication-associated protein (Rep) has been proposed for BFDV. The Rep gene of BFDV was expressed and purified, and it was shown to cleave short oligonucleotides containing the conserved nonanucleotide sequence found in the replication origin of circoviruses. This endonuclea ...

Abstract:
... Wild birds are known reservoirs of bacterial and viral pathogens, some of which have zoonotic potential. This poses a risk to both avian and human health, since spillover into domestic bird populations may occur. In Victoria, wild-caught cockatoos trapped under licence routinely enter commercial trade. The circovirus Beak and Feather Disease Virus (BFDV), herpesviruses, adenoviruses and Chlamydia ...

Abstract:
... Psittacine beak and feather disease (PBFD) is a common disease in psittacine bird that caused by beak and feather disease virus (BFDV). BFDV is widely spread and threatening psittacine birds worldwide. However, the BFDV infection in China remains largely unknown. In this study, a surveillance study of BFDV was conducted in three budgerigar breeding facilities, which showed that 66.6% of collected ...

Abstract:
... Beak and feather disease virus (BFDV) is a globally distributed pathogen of psittacine birds. In Australia, it is thought to be the dominant pathogen of Psittaciformes, and it is listed as a ‘key threatening process to biodiversity’. Infection with BFDV can cause serious and often fatal disease. However, knowledge on BFDV infection persistence in wild hosts is scarce. We investigated this in 55 wi ...

Abstract:
... Avian polyomavirus disease and psittacine beak and feather disease (PBFD) are both contagious viral diseases in psittacine birds with similar clinical manifestations and characterized by abnormal feathers. To determine the prevalence of Aves polyomavirus 1 (APyV) and beak and feather disease virus (BFDV) in captive, exotic psittacine birds in Chile, feathers from 250 psittacine birds, representing ...

Abstract:
... Pathogens can have a profound impact on the population dynamics of avian populations. Beak and feather disease virus (BFDV) is considered one of the few pathogens capable of causing extinction, because it predominantly infects the highly threatened order Psittaciformes, the signs of disease are severe, and mortality can be extremely high. Little is known about BFDV in wild populations, particularl ...
