Abstract
R factorsfi+andfi−, with various combinations of drug-resistance markers and isolated from independent sources, were transduced by phage P1kc inEscherichia coliand by phage P22 inSalmonella typhimurium. Usually the entire R factor was transduced by P1kc inE. coli, as indicated by the absence of segregation of the drug-resistance markers from their conjugal transferability. In contrast, the patterns of segregation of the drug-resistance markers and their conjugal transferability differed considerably among various R factors after transduction by P22 inS. typhimurium. Transduction frequencies varied among R factors in both transduction systems.Keywords
