the following experimental results constitute evidence that in the course of normal virus infection , a resealing reaction is rapidly instituted in the cell wall which reverses the effect of the original permeability increase , and renders the cell refractory to a second lytic reaction by a homologous virus : ( a ) cell leakage induced by t2 virus in the course of normal infection markedly slows down or stops within a few minutes , even when only a small fraction of the material potentially available for leakage has been released , ( b ) superinfection after 8 minutes at 37 degrees c. , of a cell previously infected with a homologous virus causes little or no appearance of a second leakage of cell constituents .
