Production and Characterization of Monoclonal Antibodies to Psittacine Beak and Feather Disease Virus [PDF]

Journal of Veterinary Diagnostic Investigation, 1992
Monoclonal antibodies specific for the virus that causes psittacine beak and feather disease (PBFD) were produced by fusing spleen cells from mice immunized with purified concentrated PBFD virus with mouse myeloma cell line Sp2/0. The resulting hybridomas were tested for reactivity against whole purified virus by an enzyme-linked immunosorbent assay ...

Assessment of recombinant beak and feather disease virus capsid protein as a vaccine for psittacine beak and feather disease

Journal of General Virology, 2009
Beak and feather disease virus (BFDV) is a significant pathogen of wild Australasian and African psittacine birds. We assessed the immunogenicity of recombinant BFDV capsid (recBFDVcap) to protect against the development of psittacine beak and feather disease (PBFD). Long-billed corellas ( Cacatua tenuirostris

Detection and analysis of new psittacine beak and feather disease virus (PBFDv) nucleotide sequences [PDF]

Journal of the Hellenic Veterinary Medical Society, 2018
Psittacine beak and feather disease (PBFD) affects a large number of Psittaciformes species. In this study, five White Cockatoo parrots (Cacatua alba) with clinical signs of PBFD were examined. After euthanasia, a full necropsy of parrots was performed and organs with macroscopic changes were sampled for routine histopathological evaluation. To confirm

Temporal Characterization of the Viral Load of Psittacine Beak and Feather Disease Virus in Rosy-Faced Lovebirds (Agapornis roseicollis)

Birds
Psittacine beak and feather disease virus (BFDV) is a widespread and highly pathogenic virus in parrots. The disease typically presents with feather and beak abnormalities, along with possible immune system suppression.
