[The use of mini-Mu-replicons for cloning of various structural genes of Yersinia pestis].

The possibility to clone the structural leu gene of Yersinia pestis in vivo using the mini-Mu bacteriophages with the inserted plasmid replicones has been demonstrated. The E. coli K12 transductants having obtained the Leu(+)-marker within the cloned 4.8-21 kb fragments stably inherited the leu-gene within the autonomous mini-Mu replicones. The possibility to clone other Yersinia pestis genes by the same technique has been demonstrated.
