the haemagglutination spectrum of psittacine beak and feather disease virus.a simple method for concentrating psittacine beak and feather disease virus (pbfdv) from crude feather suspensions is described. the addition of 10% polyethylene glycol (mw 6000 to 9000) to feather suspensions facilitated the precipitation and pelleting of pbfdv by low speed centrifugation. pellets were resuspended in one-twentieth of the original volume with caesium chloride (cscl) buffer and subjected to isopycnic ultracentrifugation. peak haemagglutination activity (ha) occurred at 1.35 g/ml ...199418671129
recombinant expression of a truncated capsid protein of beak and feather disease virus and its application in serological tests.beak and feather disease virus (bfdv) causes severe disease characterized by irreversible feather disorders and severe immunosuppression in many psittacine species. bfdv cannot be propagated in tissue or cell cultures, rendering virus propagation and thus diagnosis rather difficult. to develop reliable diagnostic methods, the region encoding the bfdv capsid protein c1 was cloned from an infected sulphur-crested cockatoo (cacatua galerita). phylogenetic analysis showed this gene had 76.3 to 83.2% ...200415223562
the prevalence of beak and feather disease virus infection in wild populations of parrots and cockatoos in new zealand.to determine the prevalence of beak and feather disease virus (bfdv) infection in exotic parrots and cockatoos in the wild in new zealand.200717928900
seroprevalence of psittacine beak and feather disease in wild psittacine birds in new south wales.a haemagglutination inhibition assay was used to detect antibody to psittacine beak and feather disease virus in sera from wild sulphur crested cockatoos (cacatua galerita), galahs (eolophus roseicapillus), short-billed corellas (cacatua sanguinea), eastern long-billed corellas (cacatua tenuirostris) and other psittacine birds in new south wales. the seroprevalence of psittacine beak and feather disease ranged from 41% to 94% in different flocks, indicating infection with the virus is widespread ...19938494522
