||Abstract:"N4r+-infected bacteria are lysis inhibited in mass culture, burst asynchronously starting 180 min postinfection, and release over 3,000 phage per cell." P.187 left column 2nd paragraph:"Development of N4 under conditions of high multiplicity of infection and high cell concentration
is shown in Fig. 2. With N4r+ the optical density of the culture increases for about 180 min, then the turbidity begins to fall, and, by
the 6th h of incubation, the optical density returns almost to the preinfection value."
