title: Defective interfering viruses: modulators of infection.
abstract: Defective interfering viruses are powerful modulators of infection which can completely alter the manifestation of virus disease or convert the disease into a symptomless infection. Although their structural biochemistry has been widely studied, their biology is still poorly understood, probably because its complexity has been underestimated.
