Abstract

Environmental isolates of 260 Pseudomonas aeruginosa strains were studied for resistance to mercury, cadmium, arsenic, and lead. All of the isolates were resistant to 1000 µg/ml of arsenic and lead, and most (97 percent) were resistant to 400 µg/ml of cadmium. The distribution patterns of their susceptibilities to mercury clearly revealed two peaks, and it was found that 54 percent of the environmental isolates were sensitive to mercury at concentrations greater than 10 µg/ml.
