Polyomavirus Encephalopathy in a Ducorps Cockatoo (Cacatua Ducorpsii) with Psittacine Beak and Feather Disease [PDF]

Journal of Veterinary Diagnostic Investigation, 1996
Necropsy tissues were examined from an adult wild-caught Ducorps cockatoo (Cacatua ducorpsii) with progressive neurologic signs. Of the tissue specimens selected for histologic evaluation, only the brain contained rare amphophilic, glassy intranuclear inclusions within astrocytes and some neurons.

Opportunistic sampling from the near-threatened Alexandrine parakeet uncovers genomes of a novel parvovirus and beak and feather disease virus. [PDF]

Aust Vet J
Birds are known to harbour a wide range of pathogenic viruses, including the beak and feather disease virus (BFDV; species, Circovirus parrot), which poses a significant threat to the conservation of endangered avian species. This study reports the genomic identification and characterisation of a novel psittaciform chaphamaparvovirus (PsChPV‐6) and ...

Molecular Characterisation, Tissue Distribution and Pathology of <i>Circovirus parrot</i> and <i>Gammapolyomavirus avis</i> in Naturally Coinfected Psittacine Birds in Bangladesh. [PDF]

Vet Med Int
Background and Aims Circovirus parrot and Gammapolyomavirus avis are two clinically important viruses affecting psittacine birds. Although several studies have investigated their genomic variability, pathogenesis and associated pathological features individually, understanding of the effects and pathogenesis of Circovirus parrot and Gammapolyomavirus ...

First report of psittacine beak and feather disease in imported budgerigar (Melopsittacus undulatus) chicks in Mexico

Brazilian Journal of Veterinary Pathology, 2020
This case reports an outbreak of psittacine beak and feather disease in imported budgerigars (Melopsittacus undulatus) in a breeding site in Mexico. Feather abnormalities occurred in 3-month-old budgerigars and the percentage of affected birds was 40 of ...

A non-invasive method to assess environmental contamination with avian pathogens: beak and feather disease virus (BFDV) detection in nest boxes [PDF]

PeerJ, 2020
Indirect transmission of pathogens can pose major risks to wildlife, yet the presence and persistence of wildlife pathogens in the environment has been little studied. Beak and feather disease virus (BFDV) is of global conservation concern: it can infect

Evolution of Beak and Feather Disease Virus across Three Decades of Conservation Intervention for Population Recovery of the Mauritius Parakeet

Diversity, 2021
Emerging infectious diseases (EIDs) are key contributors to the current global biodiversity crisis. Psittaciformes (parrots) are one of the most vulnerable avian taxa and psittacine beak and feather disease (PBFD) is the most common viral disease in wild

Unexpected Pathogen Diversity Detected in Australian Avifauna Highlights Potential Biosecurity Challenges

Viruses, 2023
Birds may act as hosts for numerous pathogens, including members of the family Chlamydiaceae, beak and feather disease virus (BFDV), avipoxviruses, Columbid alphaherpesvirus 1 (CoAHV1) and Psittacid alphaherpesvirus 1 (PsAHV1), all of which are a ...

Accelerometry reveals limits to use of an energy‐saving anthropogenic food source by a threatened species: A case of Carnaby's cockatoos (Zanda latirostris) and canola

Ecology and Evolution, Volume 13, Issue 10, October 2023., 2023
We used accelerometer‐capable GPS tracking to investigate the use of a novel food source by endangered Carnaby's cockatoos (Zanda latirostris) during nestling provisioning. We found the importance of canola relative to native food sources increased with increased maximum daily temperature; however, there was a threshold for time spent in canola, even ...

Metagenomic Detection of Multiple Viruses in Monk Parakeet (Myiopsitta monachus) in Australia. [PDF]

Vet Med Sci
Summary Three viruses from the families Circoviridae, Parvoviridae and Adenoviridae were detected in this study using a non‐invasive, high‐throughput sequencing method. Though their pathogenic consequences are unknown, these viruses may pose a risk of spreading infection within the pet trade.

Liver virome of a Little Corella (Cacatua sanguinea) reveals coinfection with a novel parvovirus and two beak and feather disease viruses

Australian Veterinary Journal, Volume 101, Issue 9, Page 366-372, September 2023., 2023
Emerging diseases are acknowledged as a growing threat to wildlife, with the continued identification of pathogenic and potentially pathogenic viruses in avian species resulting from ongoing advances in molecular diagnostic techniques. Parvoviruses under the genus Chaphamaparvovirus (subfamily Hamaparvovirinae) are highly divergent.
