| Abstract: | Strains of members of Enterobacteriaceae, namely Escherichia coli (18), Klebsiella aerogenes (16), and Serratia marcescens (16) were screened for Cd resistance or sensitivity. Only one strain each of these was resistant to high levels (25 n moles/0.05 ml) CdCl2. The Minimal inhibitory concentration (MIC) of sensitive strains ranged from 0.8-5 micrograms/ml. All the resistant strains were simultaneously resistant to a number of antibiotics. Treatment with sodium dodecyl sulfate eliminated resistance to Cd and to some antibiotics. |
