Polyomavirus Encephalopathy in a Ducorps Cockatoo (Cacatua Ducorpsii) with Psittacine Beak and Feather Disease

Electron microscopical observations of psittacine beak and feather disease in an Umbrella cockatoo (Cacatua alba).

Psittacine beak and feather disease (PBFD) was diagnosed in an umbrella cockatoo (Cacatua alba) with severe feather dystrophy and loss. Electron microscopically, the intranuclear and intracytoplasmic inclusion bodies observed by light microscopy were composed of viral particles forming paracrystalline arrays, whorls, semicircles or concentric circles. Recovered viral particles from the skin and...

Detection of Beak and Feather Disease Virus and Avian Polyomavirus Dna in Psittacine Birds in Poland

The first survey on the incidence of beak and feather disease virus (BFDV) and avian polyomavirus (APV) among the captive psittacine birds in Poland was presented in this study. Samples were collected between 2006 and 2009. A total number of 751 symptom–free birds from 31 genera and 59 species were tested for BFDV and APV by means of a PCR assay. BFDV was found in 25.3% and APV in 22.24% of the...

Molecular detection and characterization of beak and feather disease virus in psittacine birds in Tehran, Iran

Beak and feather disease virus (BFDV), a member of genus circovirus, is a small, non-enveloped, single stranded DNA virus. Although BFDVs are among the most well studied circoviruses, there is little to no information about BFDVs in Iran. The aim of the present study was to detect and identify BFDV molecules from the birds referred to the avian clinic of The Faculty of Veterinary Medicine, Tehr...

Prevalence of Psittacine Beak and Feather Disease Virus and Avian Polyomavirus in Captivity Psittacines from Costa Rica

Psittacine beak and feather disease virus (PBFDV) and avian polyomavirus (APV) are the most common viral diseases in psittacine birds, both affecting feathers and physical appearance of birds. Between 2005 and 2009, a total of 269 samples were collected from birds presented at veterinary clinics, shelters and rescue centers of wildlife in Costa Rica. They belonged to 19 species of psittacine bi...
