Seroprevalence of psittacine beak and feather disease in wild psittacine birds in New South Wales

Australian Veterinary Journal, 1993
SUMMARYA haemagglutination inhibition assay was used to detect antibody to psittacine beak and feather disease virus in sera from wild sulphur crested cockatoos (Cacatua galerita), galahs (Eolophus roseicapillus), short‐billed corellas (Cacatua sanguinea), eastern long‐billed corellas (Cacatua tenuirostris) and other psittacine birds in New South Wales.

Experimental reproduction of psittacine beak and feather disease/French Moult

Avian Pathology, 1987
Nestling budgerigars and galahs and one-day-old SPF chickens were inoculated with an homogenate prepared from the feathers of a variety of birds with psittacine beak and feather disease (PBFD), and known to contain virus-like particles 20 nm in diameter.

Genetic Diversity of Beak and Feather Disease Virus Detected in Psittacine Species in Australia

Virology, 2001
The complete nucleotide (nt) sequence of eight isolates of beak and feather disease virus (BFDV) obtained from a range of psittacine species with psittacine beak and feather disease (PBFD) from throughout Australia were compared with the sequences of two BFDV isolates previously reported from Australia (BFDV-AUS) and America (BFDV-USA), respectively ...

Routes and prevalence of shedding of psittacine beak and feather disease virus

American Journal of Veterinary Research, 1991
SUMMARY Psittacine beak and feather disease (pbfd) virus was recovered from the feces and crop washings from various species of psittacine birds diagnosed with pbfd. High concentrations of the virus also could be demonstrated in feather dust collection from a room where 22 birds with active cases of pbfd were being housed.

Survey of Captive Parrot Populations Around Port Phillip Bay, Victoria, Australia, for Psittacine Beak and Feather Disease Virus, Avian Polyomavirus and Psittacine Adenovirus

Australian Veterinary Journal, 2015
OBJECTIVE: This study investigated the prevalence of psittacine beak and feather disease virus (BFDV), avian polyomavirus (APV) and psittacine adenovirus (PsAdV) in captive psittacine birds around Port Phillip Bay, Victoria, Australia.

Psittacine beak and feather disease infected cells show a pattern of apoptosis in psittacine skin

Avian Pathology, 1998
Skin biopsies from 23 birds with psittacine beak and feather disease (PBFD) were examined by light and electron microscopy. Affected cells, preferentially found in the cell layers of the feather follicles, could be clearly identified by the presence of intracytoplasmic virus inclusion bodies.

Characterization of a new virus from cockatoos with psittacine beak and feather disease

Virology, 1989
A novel virus isolated from the feather follicles of cockatoos diagnosed as having psittacine beak and feather disease was characterized by electron microscopy, nucleic acid content, and polypeptide composition. Purified virions displayed an icosahedral symmetry, were nonenveloped, and had a mean diameter of 14 to 16 nm negatively stained.

Survey of Beak and Feather Disease Virus (BFDV) in Guatemalan Neotropical Psittacine Birds.

Journal of Avian Medicine and Surgery, 2021
Beak and feather disease virus (BFDV), a circovirus, is the etiologic agent of psittacine beak and feather disease (PBFD), a progressive and often fatal disease in Psittaciformes. Even though neotropical psittacine species are more resistant to clinical infection than Old World species, BFDV is recognized as a threat to immunologically naïve wild ...

Evidence of Psittacine Beak and Feather Disease Virus Spillover Into Wild Critically Endangered Orange-Bellied Parrots (Neophema Chrysogaster).

Journal of Wildlife Diseases, 2014
We report the recent emergence of a novel beak and feather disease virus (BFDV) genotype in the last remaining wild population of the critically endangered Orange-bellied Parrot (Neophema chrysogaster).

Laboratory diagnosis of psittacine beak and feather disease by haemagglutination and haemagglutination inhibition

Australian Veterinary Journal, 1993
SUMMARYSimple and sensitive haemagglutination and haemagglutination Inhibition assays were developed for psittacine beak and feather disease (PBFD) virus and serum antibody, respectively. The assays were used in the examination of samples from 73 birds clinically affected with PBFD.
