Psittacine Polyomavirus Most commonly this is recognised in chicks in the nest. Swollen bellies, tremors, wobbly, abnormal feathers may be seen. Larger psittacine species may live longer and show diarrhoea or regurgitation. Classical infections seem to affect larger species at around 7 weeks on age and can kill within a few hours of the first signs. Adult birds are also affected. Signs resemble those of septicaemia and hepatitis. Embryonic death or decreased hatchability can also be caused by Polyomavirus. Please use or at the very least liaise with your avian vet. Interpreting what the test means to you and your birds and what if any action is required in your situation needs veterinary input. We can assist your vet but we cannot get involved with cases directly. |
