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
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
vaccination and challenge studies with psittacine beak and feather disease virus.psittacine beak and feather disease virus (pbfdv) was administered to adult galahs (eolophus roseicapillus) by mouth or by intramuscular injection. concentration of pbfdv antibodies in serum and excretion of pbfdv were monitored by haemagglutination inhibition (hi) and haemagglutination (ha) respectively. after oral administration, 17 of 18 galahs remained clinically normal and a small rise in antibody titre was detected in 3 of 18 birds. after intramuscular administration, antibody was detected ...19938117208
