Four species-specific anti-IgY secondary antibodies were used in the assays: goat anti-macaw IgY, goat anti-bird IgY, goat anti-duck IgY, and rabbit anti-chicken IgY.Results: In the Western blot, anti-macaw IgY secondary antibody produced strong signals with Blue and gold macaw and Cockatiel positive plasma, but no signal with Mallard positive plasma. Anti-bird IgY secondary antibody produced strong signals with Blue and gold macaw, Cockatiel, and Mallard positive plasma. Anti-duck and anti-chicken IgY secondary antibody produced a strong and moderate signal, respectively, only with Mallard positive plasma. In the dot-blot ELISA, there was a distinct and significant difference (P<0.05) in the signal intensity between the different secondary antibodies within a bird species. Anti-macaw IgY secondary antibody produced significantly (P<0.05) stronger signals than the other secondary antibodies in Blue and gold macaw, Cockatiel, and Monk parakeet positive plasma, while anti-duck IgY secondary antibody produced significantly (P<0.05) stronger signals than the other secondary antibodies in Mallard positive plasma.Conclusion: In testing psittacines with immunoassays, and especially in assays that incorporate short incubation reaction times such as a dot-blot ELISA, species-specific anti-IgY secondary antibodies provided more accurate results.Keywords: immunodiagnostics, serology, proventricular dilatation disease, avian ganglioneuritisEscandon PHeatley JJBerghman LRTizard IMusser JMBDove Medical Pressarticleimmunodiagnosticsserologyproventricular dilatation diseaseavian ganglioneuritisVeterinary medicineSF600-1100ENVeterinary Medicine: Research and Reports, Vol Volume 10, Pp 141-150 (2019)
