## Abstract Defective interfering (DI) virus is simply defined as a spontaneously generated virus mutant from which a critical portion of the virus genome has been deleted. At least one essential gene of the virus is deleted, either in its entirety, or sufficiently to make it nonβfunctional. The re
Defective-interfering (DI) viruses arise spontaneously by deletion mutations. The shortened genomes of the DI particles cannot replicate unless they coinfect a cell with a wild-type virus. Upon coinfection, the DI genome replicates more quickly and outcompetes the wild type. The coinfected cell prod
