[Immunoenzyme analysis of adenovirus hexon. Determination of antibodies from hyperimmunized chickens]
We have elaborated three systems of enzyme-linked immunosorbent assay (ELISA) for detection of chicken IgG antibodies specific for hexon antigens of three immunologically distinct adenovirus groups: those of mammalian adenoviruses (Mastadenovira), typical avian adenoviruses (Aviadenovira) and of egg-drop syndrome-76 (EDS-76) virus. In each system the antibodies against respective hexons were specifically detected. In mammalian adenovirus hexons the ELISA detects primarily the type-specific (epsilon) and genus-specific (alpha) antigenic determinants. The time course of anti-hexon antibodies content was followed during immunization. The level of anti-hexon antibodies in egg yolk reflects adequately their content in blood serum. The technique is suitable for serological diagnosis of chicken adenoviral infections as well as for characterization of egg-yolk antibodies obtained by preparative hyperimmunization of hens.
