title: [Construction of variants of Yersinia pestis EV76 (RIEG line) vaccine strain differing in antibiotic resistance spectra with stage-by-stage transduction of R-transposons].
abstract: Mono- and polyresistant variants of the plague vaccinal strain Yersinia pestis EV76 (RIEG line) were constructed with stage-by-stage transduction of transposons Tn5, T, Tn10 and Tn9 located in the phage vectors. Methods for stage-by-stage selection of the transductants that preserved intact determinants of surviving, antiphagocytic activity and immunogenic properties were designed for their further testing as model vaccinal strains in combined specific and emergent medicamentous prophylaxis of plague.
