“…Avian polyomavirus infection: APV infection causes acute death, abdominal distention, and feather abnormalities known as "French molt" in fledgling and young budgerigars [34]. It also causes a loss of down feathers on the back and abdomen, filoplumes on the head and neck, and subcutaneous hemorrhage of nesting budgerigars [5,16].…”

“…In Italy and Taiwan, the viral DNA positive rates were 0.8% and 15.2%, respectively. In Japan, APV infections have been reported in several bird species, such as budgerigar, black-headed caique (Pionites melanocephala) and eclectus parrot (Eclectus roratus) [34,47], with an overall DNA positive rate of 2.7% [69].…”

“…However, these changes can also be associated with other infectious and non-infectious diseases. Recently, APV has been identified by immunofluorescent antibody staining [28], in situ hybridization [79], electron microscopy [34], virus-neutralization test [74], PCR [70,75], and realtime PCR [45].…”

ABSTRACT. To date, several DNA viral infections have been reported in psittacine birds. Psittacine beak and feather disease (PBFD) is characterized by symmetric feather dystrophy and loss and development of beak deformities. PBFD is caused by beak and feather virus, which belongs to the Circoviridae, and is the most important infection in psittacine birds worldwide. Avian polyomavirus infection causes acute death, abdominal distention, and feather abnormalities. Pacheco's disease (PD), which is caused by psittacid herpesvirus type 1, is an acute lethal disease without a prodrome. Psittacine adenovirus infections are described as having a clinical progression similar to PD. The clinical changes in psittacine poxvirus-infected birds include serious ocular discharge, rhinitis, and conjunctivitis, followed by the appearance of ulcerations on the medial canthi of the eyes. Internal papillomatosis of parrots (IPP) is a tumor disease characterized by progressive development of papillomas in the oral and cloacal mucosa. IPP has been suggested to caused by papillomavirus or herpesvirus. However, information about these diseases is limited. Here we review the etiology, clinical features, pathology, epidemiology, and diagnosis of these DNA viruses.KEY WORDS: DNA virus, psittacine bird, review.

“…Budgerigar fledgling disease (BFD), a contagious disease causing high mortality in fledgling budgerigars (Melopsittacus undulatus), was first reported in the United States 5 and Canada 1 and subsequently has been recognized in other countries 11,14,19,22,23 The causative agent was identified as a papovavirus and has been characterized as the first nonmammalian member of the polyomavirus genus. 3,16 In addition, papovavirus infection of numerous other bird species has been described.…”

“…Egg transmission of the agent was suggested by Bernier et al (1981). They also hypothesised that French Moult of budgerigars was a milder form of the same infection, a suggestion supported by the later work of Hirai et al (1984). Papovavirus-like agents have also been associated with acute disease in fully-fledged lovebirds in Australia (Pass, 1985) and have been implicated in the deaths of other psittacine species in the USA (Jacobsen et al, 1984).…”

SUMMARYOutbreaks of a disease in two budgerigar aviaries caused 20% and 53% mortality respectively in recently hatched chicks during the 1985 breeding season. Clinical signs were first observed at 5 to 7 days of age. In most birds darkening of the normal skin colour was followed by death in 2 to 10 days. In individual nests all or part of a hatch could be affected. Occasional survivors had abnormal plumage. Few gross lesions were found àt post-mortem examination. Histologically, many large basophilic intranuclear inclusions were present in multifocal degenerative lesions throughout the epidermis, kidney, heart, brain and other tissues. These inclusions were shown by transmission electron microscopy to contain numerous virus particles which, on direct examination, had a .diameter of 46 to 56 nm and a papovavirus-like morphology. These outbreaks were considered to be cases of budgerigar fledgling disease, a syndrome that has been reported in other countries but not previously described in Great Britain.
