Summary
Avian bornaviruses, particularly parrot bornaviruses (PaBVs), cause proventricular dilatation disease (PDD) in birds. This review covers their taxonomy, disease, diagnosis, and control measures.
Area of Science:
- Veterinary Virology
- Avian Pathology
Background:
- Avian bornaviruses (ABVs) are diverse viruses in the genus Orthobornavirus.
- First detected in psittacines in 2008, ABVs are now found in passerines and waterbirds.
- Parrot bornaviruses (PaBVs) are significant veterinary pathogens causing proventricular dilatation disease (PDD).
Purpose of the Study:
- To provide a comprehensive review of avian bornavirus infections.
- To summarize current knowledge on ABV taxonomy, pathogenesis, epidemiology, diagnostics, and control.
- To highlight the veterinary importance of PaBVs and PDD.
Main Methods:
- Literature review of scientific publications on avian bornaviruses.
- Synthesis of information on viral characteristics, disease mechanisms, and host responses.
- Compilation of data on diagnostic techniques and potential countermeasures.
Main Results:
- Avian bornaviruses encompass at least 15 distinct viruses.
- Proventricular dilatation disease (PDD) in psittacines is characterized by neurological and gastrointestinal dysfunction.
- Knowledge gaps exist regarding the pathogenicity of passerine and waterbird bornaviruses.
Conclusions:
- Avian bornaviruses represent a significant threat to avian health, especially in captive populations.
- Further research is needed to understand and control infections caused by less-studied ABV strains.
- This review consolidates current understanding and identifies areas for future investigation in avian bornavirus research.
