All diseases
Avian Bornavirus / PDD
What it is
Avian Bornavirus is associated with Proventricular Dilatation Disease (PDD), a serious condition affecting the nervous system and digestive tract.
How it spreads
Likely spread through feces and other secretions; transmission dynamics are still being studied.
Why it matters
PDD is often fatal and difficult to manage; carriers may be asymptomatic.
Common signs or symptoms
- Regurgitation or vomiting
- Undigested food in droppings
- Weight loss
- Neurological signs such as weakness or tremors
Testing and diagnosis
PCR and serology on cloacal swabs, blood, or feces.
What to do if exposure is suspected
Quarantine and consult an avian vet experienced with PDD.
Quarantine considerations
Quarantine new birds and consider testing before introducing them to a flock.
When to contact an avian veterinarian
See an avian veterinarian as soon as neurological or digestive symptoms appear.
When to contact animal health authorities
Contact authorities for larger outbreaks affecting multiple owners or facilities.
