以鼠伤寒沙门氏菌为模板，将Episome FT21基因转入无齿沙门氏菌。以沙门氏菌转化前体噬菌体ϵ15、ϵ34和g341为供体，通过基因重组和合子诱导实验将其定位在宿主染色体上。前噬菌体ϵ34在靠近纯基因座的位置附着或整合到寄主染色体上，而前噬菌体ϵ15和g341分别位于His和Lys之间以及His和Gua之间。关于噬菌体转换基因的来源，我们讨论了这些发现的意义。
An episome FT21 was transferred into Salmonella anatum from Salmonella typhimurium. By means of the resulting male strains as donors, Salmonella conversion prophages ϵ 15, ϵ 34, and g 341 were mapped on the host chromosome by genetic recombination and zygotic induction experiments. Prophage ϵ 34 was shown to be attached to or integrated into the host chromosome at a site close to the purE locus, whereas prophages ϵ 15 and g 341 were located near each other at sites between his and lys and between his and gua, respectively. The implications of these findings are discussed in regard to the orgin of the phage conversion genes.
