RESUMO
Genetic mapping of ribosomal protein cistrons of Salmonella typhimurium and Escherichia coli was performed by phage P1 mediated, generalized transduction. From an E. coli hybrid strain which carried a S. typhimuirum F′ factor, an E. coli strain was constructed which had integrated S. typhimurium genetic material including the region of the strA locus. Salmonella genetic material from this hybrid was transduced into E. coli recipients. The ribosomal protein electrophoretic patterns of these hybrid transductants were correlated with the presence of markers contributed by each parent.
