title: Serological cross-reactivity of avian adenovirus serotypes in an enzyme-linked immunosorbent assay.
abstract: Fowl adenoviruses free of avian adenovirus-associated virus, representing 10 serotypes, were tested for cross-reactivity in an enzyme-linked immunosorbent assay (ELISA). All antigens and antisera prepared in chickens, along with uninfected control antigen and normal chicken serum, were reacted in a checkerboard pattern with ELISA. There was considerable cross-reactivity among all serotypes tested. Homologous reactions were generally, but not always, stronger than heterologous reactions. ELISA was about as sensitive as virus neutralization in detecting antibodies. The high sensitivity plus broad-spectrum reactivity should make ELISA a preferred test for the detection of adenovirus antibodies in poultry flocks.
