Immunofluorescent study on egg-adapted avian encephalomyelitis virus infection in chickens.
Fluorescent antibody study showed persistent infection of egg-adapted avian encephalomyelitis virus in the central nervous system and pancreatic tissues of infected embryos and chickens hatched from them. The limited organ tropism of the egg-adapted virus in hatched chickens was in striking contrast to the systemic infection that occurs with a field strain. In chidkens orally infected with egg-adapted virus strains, transient infection of a few organs was found despite occurrence of viremia.
