Occurrence of antibodies against insect virus proteins in mammals: simple model to differentiate between passive exposure and active virus growth.

摘要

Antibodies against an "enterovirus-like" virus of insects, cricket paralysis virus, occur in the sera of domestic animals. When these antibodies were used in combination with the immunoprecipitation of radiolabeled virus proteins from infected Drosophila cells in culture, it could be demonstrated that the animals were exposed to preformed virus.
