Se hela listan på talk.ictvonline.org Avian polyomavirus (APV) infections have been reported to cause fatal disease in a wide range of psittacine species. Here we demonstrate APV infections in buzzards (Buteo buteo) and in a falcon (Falco tinnunculus) found dead in Germany, and in lovebirds (Agapornis pullaria) with fatal disease, wild-caught in Moçambique. An avian polyomavirus has been reported as the most common infectious agent causing death in unvaccinated young psittacine birds in the United States. Some affected birds die without developing any clinical signs of disease, while others die 12-to 48-hours after developing clinical signs that may include depression, loss of appetite, weight loss, delayed crop emptying, vomiting, diarrhea and Avian polyomavirus (APV) causes a range of disease syndromes in psittacine birds, from acute fatal disease to subclinical infections, depending on age, species, and other unidentified risk factors. Avian polyomavirus is, like PBFD, a contagious livestock disease which is highly underestimated, despite being responsible for feather deformations and premature death in chicks.

Polyomavirus birds

Macaws, eclectus, lovebirds, caiques, and conures are particularly susceptible. How can I tell if my bird has been exposed to avian polyomavirus? Avian polyomavirus is a very serious disease in birds causing depression, dehydration, and haemorrhaging under the skin. It is of particular interest to anyone who breeds birds in captivity, as most deaths occur in new hatchlings and birds up to five months of age. The Avian polyoma virus (also known as Budgerigar Fledgling Disease) causes high levels of mortality in young psittacine birds.

On the other hand, adults are likely to develop a level of immunity to the virus. Morphological studies show polyomavirus as a circular, non-enveloped icosahedral (20 faces) virus with a double-stranded DNA genome.

Polyomavirus is a deadly infection that affects many of the bird's body parts and organs simultaneously. This infection affects caged birds, especially those from the parrot family. Young birds from newborn to juveniles (14-56 days), are the birds most at risk and is usually fatal.

In its acute form, it usually results in nest mortality. In its chronic Polyomavirus goes by a number of other names, the most recognised name being Budgerigar Fledgling Disease or Papovavirus. It was first reported in 1981 in the US and Canada ( but probably was in aviaries long before this ).

Avian polyomavirus (APV) infections have been reported to cause fatal disease in a wide range of psittacine species.

Experts note that polyomavirus in birds is notorious among neonates from 14-56 days of age.

One or more APVs are suspected to infect nonpsittacine cage birds, but the relationship of these viruses to the APV infecting parrots remains unclear.

In Australia, flocks of wild cockatoos may have a disease prevalence of 20% and a seroprevalence of 60% to 80% and infection is probably maintained in a population by diseased birds and contaminated nest hollows. Avian Polyomavirus APV is a deadly infection that affects many of the bird's body parts and organs simultaneously. This infection affects caged birds, especially those from the parrot family. APV is one of the most significant pathogens of domestically raised psittacine birds (parrots).

Avian polyomavirus is, like PBFD, a contagious livestock disease which is highly underestimated, despite being responsible for feather deformations and premature death in chicks. Avian polyomavirus (PVA - papovaviridae family) mostly affects young birds still in the nest (parakeets, amazons, eclectus, macaws, conures). In its acute form, it usually results in nest mortality.

Wild birds are believed to constitute the natural reservoir for influenza A virus. En jämförelse mellan circovirus och polyomavirus hos sällskapspapegojor pose a threat to ecosystems, where especially birds are susceptible to toxic effects.
