| [transduction of plasmid antibiotic resistance determinants with pseudo-t-even bacteriophages]. | transduction of antibiotic resistance determinants of the plasmid pbr322 with pseudot-even bacteriophages rb42, rb43, and rb49 was studied. it is established that antibiotic resistance determinants of plasmid pbr322 from escherichia coli reca(+)- and reca(-)-donor strains do not differ significantly in respect to the efficiency of transduction. amber mutants rb43-21, rb43-33, and a double amber mutant rb43am21am33 were obtained. these mutants facilitated transduction experiments in some cases. t ... | 2003 | 12942776 |
