ABSTRACT
In order to establish a method by which the recombinant suicide plasmids integrated on the chromosome could be recircled, A simple method of transconjugative cloning was established with the helper plasmids pMT999 or pRK2013 and fusion strains of Shigella flexneri which were obtained by screening with in vivo expression technology. And the cloning efficiency with this method is very high.
