Polyomavirus är DNA-baserade (dubbelsträngat DNA), små (40-50 nanometer i diameter), ikosaedriska till formen och saknar lipoproteinskal. De är potentiellt onkogena (dvs tumörskapande ), de fortlever ofta som en latent infektion i ett värddjur utan att orsaka sjukdom, men kan orsaka tumörer i ett värddjur av en annan art eller hos en individ med försämrat immunförsvar . This means keeping your bird away from pet shops, bird marts, and bird shows where it may be exposed to strange birds of unknown health status. Whenever you buy a new bird, it is best to test this bird for polyomavirus and keep the bird in an isolation area, away from other birds in the household, for a period of at least 60 days.

Polyomavirus, (family Polyomaviridae), any of a subgroup of minute oncogenic DNA viruses of the family Polyomaviridae. The virus was first isolated in 1953 when the murine polyomavirus was discovered to have caused tumours in laboratory mice. Avian polyomavirus is a virus that may cause serious disease or even death in cage birds, particularly in the case of young chicks between one week to two mo Polyomavirus is a type of infection that can affect different parts of a bird’s body as well as their organs. While it can affect adult parrots, it’s more commonly seen in younger birds from the age of 14-56 days of age. Until now, prevention of polyomavirus infection in psittacine birds could only be accomplished through strict isolation to reduce potential exposure to the virus. The USDA-registered inactivated avian polyomavirus vaccine can safely be used to protect vaccinates from infection and control spread of … Methods for preventing avian polyomavirus infection in a bird classified as being a member of the Psittaciformes order are also provided.

Birds that are infected but do not develop signs of disease will become viremic and may begin shedding virus through the cloaca and possibly oral mucosa. Rarely, viremia lasts for months. Fecal shedding lasts for up to 16 weeks, but again is much shorter in adult birds and nestlings that are infected at an older age. Polyomavirus Vaccine Beak and feather disease (psittacine circovirus) and Budgerigar fledgling disease (avian polyomavirus) are viral diseases that can frequently affect captive psittacine birds. We designed the first survey to investigate the presence of beak and feather disease virus (BFDV) and Avian polyomavirus (APV) inside the population of captive psittacine birds in Italy. Avian polyomavirus (APV) infection, also called as budgerigar fledgling disease (BFD) causes various health problems in many psittacine species which may cause untimely death.

It is considered one of the most significant threats to cage birds around the world.
