[The multiple effect of plasmid RP4::Mu cts 62 in transcipient bacilli].

Transfer of conjugative hybrid plasmid RP4::Mu cts 62 from Escherichia coli into Bac. cereus, Bac. thuringiensis, Bac. mesentericus and Bac. polymyxa cells led to the multiple effects on the structure and physiology of bacillus cells. It has resulted in a decrease of the bacillus vitality, in the accelerated autolytic decay of cells, in the delay of cell growth and reproduction rate in liquid and solid media, in the disruption of ultrastructure of the cell membrane and its surface layer.
