Interference and Cell Protection by Poliomyelitis Virus in Tissue Culture

Abstract

RECIPROCAL interference between strains of the three recognized types of poliomyelitis virus has been reported by Ledinko1, using roller-tube cultures of monkey testicular tissue. In her experiments, both the ‘interfering’ and the ‘excluded’ virus were fully cytopathogenic, and there was no suggestion of any mutual inhibition of their degenerative effects on the cells. Prevention of growth of the second virus, as shown by titration in the presence of type-specific antiserum against the first, was apparently the result of pre-emptive infection and subsequent destruction of susceptible cells by the first virus. The purpose of this communication is to describe a further example of interference among poliomyelitis viruses, in which a more direct recognition of the effect was made possible by the peculiar cytopathogenic behaviour of the interfering virus.
