title: Detection of antibody to Bordetella avium using a particle concentration fluorescence immunoassay (PCFIA).
abstract: A fluorescent assay for detection of antibody to Bordetella avium was developed and evaluated against current serological techniques. Bordetella antigen was coated on submicron polystyrene beads and used in an antibody sandwich technique with commercially available goat anti-turkey fluorescein-labeled IgG. Positive control sera were taken from turkeys from which B. avium was isolated. Negative control sera were from turkeys from which no B. avium was isolated and which tested negative by agglutination and enzyme immunoassay. A commercial fluorescence concentration analyzer was used to quantitate the epifluorescence in a special 96-well plate designed to minimize background fluorescence. The particle concentration fluorescence immunoassay was found to be as sensitive as the enzyme immunoassay, with good reproducibility. It required less time and smaller quantities of sample and reagents.
