Abstract

When the osmotic pressure of the maintenance medium is decreased, poliovirus reproduction is inhibited. Poliovirus strains may vary in their sensitivity to the effect of hypotonic solutions. Mutants have been selected (designated as osm mutants) the reproduction of which is characterized by particularly high resistance to media with reduced osmotic pressure. Initial stages of the virus-cell interaction proceed at similar rates in physiologic and hypotonic solutions. Reactions sensitive to hypotonic solutions take place in the second half of the latent period and during the stage of virus maturation. The multiplication of viruses in moderately hypotonic solutions exhibits a marked dependence upon the temperature and the presence of cystine in the medium, even though these factors have relatively small influence upon the reproduction of the viruses in isotonic solutions. Despite complete cessation of the production of infectious virus in certain hypotonic media, there is a considerable synthesis of virus-induced RNA. At least some of the RNA produced under these conditions is infectious. With a further decrease of the osmotic pressure of the medium the synthesis of the viral RNA is inhibited. Some possible explanations of the observed facts are briefly discussed.
