A chimeric beta-lactamase encoding plasmid, containing the 4.4 Mdal beta-lactamase plasmid and the 2.6 Mdal cryptic plasmid of Neisseria gonorrhoeae has been characterized by physical and biological methods. Digestion with restriction enzymes indicates the presence of the following restriction sites
The toxic effects of 2,4-dichlorophenol on two strains of Escherichia coli harbouring plasmids with p-lactamase activity were studied. The toxicant had a significant effect on growth at concentrations of 12 p g mi-' for the JA 221 (pBR322) strain, as well as at 24 pg rnl-' for the 55-3 (RP4) strain.
