Derzsy's disease
A fatal parvovirus infection of young geese.
Last updated
Derzsy's disease is a viral infection of geese caused by Goose parvovirus. It is notable for causing high mortality in young goslings, with clinical disease limited to birds under five weeks of age. Transmission occurs horizontally through the faecal-oral route and indirectly via contaminated objects, as well as vertically from breeder birds to eggs.
Quick Facts

Clinical signs and diagnosis
Acutely affected goslings may show prostration and die rapidly, with limited clinical signs. Older birds exhibit severe systemic and neurological signs, diarrhoea, reduced feed intake, excessive water intake, swollen eyelids, eye and nasal discharge, white diarrhea, a membrane covering the tongue, loss of down, and reddening of the skin. Diagnosis is confirmed by viral isolation, immunofluorescence, electron microscopy, or pathological changes.
Did You Know?
- Several genotypes of Goose parvovirus have been described, based on the sequence of the VP3 protein.
- Infected birds shed high concentrations of the virus in their droppings, contaminating feed, water, and bedding.
- Vertical transmission can lead to outbreaks in hatcheries.
