The Transfer of Defective LambdaLysogeny between Strains of Escherichia coli

Abstract

SUMMARY: The infective transfer of defective lambda lysogeny from a defective prophage to sensitive Escherichia coli has been observed. The agent of transfer appears to be lambda phage in which has been incorporated the hereditary defective element. It is concluded that the existence of the phage genes responsible for defective lysogeny is not limited to the prophage condition.
