Beak and feather disease virus and Chlamydiales infections in wild Australian psittacines: no statistical evidence for dependence

, 2021
Wildlife can be hosts for pathogens of conservation and zoonotic concern. Infection with one pathogen can increase the risk of co-infection with others, with resulting impacts on hosts, for example on body condition or survival.

Development of a Lentiviral-Based Expression System Targeting the Conserved Domain of the Rep Gene of Psittacine Beak and Feather Disease Virus

Jentashapir Journal of Cellular and Molecular Biology
Background: Psittacine beak and feather disease virus (PBFDV) causes severe immunosuppression and feather abnormalities in psittacine birds, and no effective antiviral treatments are currently available. RNA interference (RNAi) has emerged as a promising

Dancing with foxes: More‐than‐human design in ‘the chicken city’

Transactions of the Institute of British Geographers, Volume 50, Issue 2, June 2025.
Abstract Urban chicken‐keeping is on the rise in London, in private gardens, community gardens, allotments, schools, and urban farm projects. In welcoming chickens into the city, urban spaces are being transformed: coops are being built, runs constructed, chicken‐friendly flora introduced, and space landscaped to accommodate both chickens and humans ...

NF2 is Essential for Human Endoderm Development

Advanced Science, Volume 12, Issue 17, May 8, 2025.
This study demonstrates that NF2, moesin‐ezrin‐radixin like (MERLIN) tumor suppressor (NF2) is essential for human endoderm formation. NF2 knockout human induced pluripotent stem cells fail to form endoderm both in vitro and in vivo due to yes‐associated protein 1 (YAP1) nuclear translocation, redirecting differentiation toward myofibroblast‐like cells.

Unusual fatal avian polyomavirus infection in nestling cockatiels (Nymphicus hollandicus) detected by nested polymerase chain reaction

Veterinární Medicína, 2007
High mortality of nestling cockatiels (Nymphicus hollandicus) was observed in one breeding flock in Slovakia. The nestling mortality affected 50% of all breeding pairs. In general, all the nestlings in affected nests died.

Temporal Loss of Genome‐Wide and Immunogenetic Diversity in a Near‐Extinct Parrot

Molecular Ecology, Volume 34, Issue 9, May 2025.
ABSTRACT Loss of genetic diversity threatens a species' adaptive potential and long‐term resilience. Predicted to be extinct by 2038, the orange‐bellied parrot (Neophema chrysogaster) is a critically endangered migratory bird threatened by numerous viral, bacterial and fungal diseases.

Circovirus infection in Croatian population of Eurasian griffon vultures (Gyps fulvus)

Scientific Reports
Circoviruses cause diseases in a wide range of hosts, including avian species. One of the most studied circoviruses is beak and feather disease virus (BFDV), which has spread worldwide due to global trade of birds and characteristics of the virus that ...

Mutability dynamics of an emergent single stranded DNA virus in a naïve host.

PLoS ONE, 2014
Quasispecies variants and recombination were studied longitudinally in an emergent outbreak of beak and feather disease virus (BFDV) infection in the orange-bellied parrot (Neophema chrysogaster). Detailed health monitoring and the small population size (
