WebApr 1, 1985 · Plasmid-encoded resistance may provide organisms with efflux and bypass mechanisms, enzymes which catalyze the transformation of metals to volatile forms, or make the bacterial cell wall impermeable to the metal (s). A problem still remains in actually defining the concentrations that distinguish metal-resistant from metal-sensitive bacteria. WebThe growth of protozoa, in turn, was dependent on bacterial copper sensitivity. The phagocytosis of bacteria induced upregulation of Dictyostelium genes encoding the … cow ste chart
