Abstract
Evidence is presented to show that cells of Escherichia coli O26:B6 infected with E. coli O111 phage D-1 exhibited a greater lysogenic response if the temperature, shortly after infection, was lowered from 37 °C. Under the same conditions, lysogeny among survivors was reduced markedly at 45 °C. Cooling the system to 20 °C prior to infection increased both the survival rate and lysogenic response among phage-infected survivors. Appropriate treatment with chloramphenicol increased both survival rate and lysogenic frequency.
