  • Title: [Transduction ability of mutants of phage CP51, virulent for bacteria of the Bacillus cereus group].
    Author: Koretskaia NG, Svetoch Oe, Kachaturian SV, Dobrina AP.
    Journal: Genetika; 1989 Jun; 25(6):1013-20. PubMed ID: 2509285.
    Abstract:
    The virulent phage CP51 used usually to transfer chromosomal and plasmid markers between bacteria of the Bacillus cereus group was treated with N-methyl-N'-nitro-N-nitroguanidine. Mutants with reduced viability and ts-mutants were isolated. Some of the mutants were found to have an increased efficiency of transduction and allow to simplify the process. Transfer frequencies of the plasmid pBC16 by the phages CP51-26 and CP51-4-59 were 5 x 10(-4) per plaque-forming unit and 4-5 x 10(-3) per bacterial cell, respectively. Possibilities of further increasing the transduction efficiency of Bacillus thuringiensis genetic material using phage CP51 mutants are discussed.
