Avian Polyomavirus Expression Patterns of Bicistronic Late mRNAs
Virology, 2009 Avian polyomavirus (APV, previously called budgerigar fledgling disease virus, BFDV-1) differs from other polyoma viruses by a complex arrangement within its late genes: p(L1)-promoted agno-genes 1a and 1b overlap p(L2)-promoted agno-genes 2a and 2b in different reading frames, and are located upstream of standard late VP genes.

Molecular Characterizations of Avian Polyomavirus Isolated From Budgerigar in China
Avian Diseases, 2008Budgerigar fledgling disease is an acute viral infectious disease caused by avian polyomavirus (APV). In this study, 34 liver tissue samples of young, dead budgerigar with typical symptoms were collected in 2004. All the samples had positive polymerase chain reaction (PCR) test based on the VP1 specific primers.

First Detection and Molecular Characterization of Avian Polyomavirus in Young Parrots in Pakistan [PDF]
Veterinary Research Communications, 2019 Avian polyomavirus (APV) infection, also called as budgerigar fledgling disease (BFD) causes various health problems in many psittacine species which may cause untimely death. The aims of this study were to investigate, for the first time, the detection, molecular characterization and phylogenetic analysis of avian polyomavirus (APV) in Pakistani ...

Genetic Diversity in Twenty Variants of the Avian Polyomavirus
Avian Diseases, 1999To determine if different pathotypes of the avian polyomavirus (APV) exist and to compare the genomes of APVs originating from different geographic areas, dates, and species of birds, the partial sequences of 18 APVs were determined. New viral sequences were compared with three published APV sequences.

Laboratory Reporting Accuracy of Polymerase Chain Reaction Testing for Avian Polyomavirus
Journal of Avian Medicine and Surgery, 2013Polymerase chain reaction (PCR) assays are available for detection of birds infected with avian polyomavirus (APV). Several laboratories offer this diagnostic assay in the United States, but little information is available regarding assay sensitivity, specificity, and accuracy.

Safety, immunogenicity, and efficacy of an inactivated avian polyomavirus vaccine
American Journal of Veterinary Research, 1998SUMMARY Objective To determine safety, immunogenicity, and efficacy of an inactivated avian polyomavirus vaccine in nonbudgerigar psittacine birds that varied in age, species, and immunologic status. Animals Safety of the vaccine was evaluated in 1,823 psittacines representing more than 80 species.

Journal of Veterinary Medical Science, 2006 Although birds infected with avian polyomavirus (APV) subclinically could be a source of infection, no epidemiological studies of APV in psittacine birds have been reported in Japan. In the present study, we investigated subclinical morbidity rate of APV in imported and domestically bred psittacine birds by polymerase chain reaction (PCR).

Characterization of the Avian Polyomavirus-Associated Glomerulopathy of Nestling Parrots
Avian Diseases, 1996The glomerulopathy occurring in nestling nonbudgerigar parrots with avian polyomavirus (APV) disease was examined in 10 parrots. Glomerular lesions were characterized by the presence of dense, periodic acid-Schiff (PAS)-positive material that expanded the mesangium and that narrowed and at times occluded capillary lumina.
