✦ Synopsis

Thirty nine clinical isolates of Acinetobacter belonging to six species were tested for resistance to 20 metal ions and their ability to produce fl-lactamase. Fifty two percent of the strains produced/~-lactamase. ~Lactamase producers and non-producers were almost equally distributed in the different species. A. baumannii was the predominant biotype and was found to be most resistant to metals. Resistance to mercury was prevalent in ~-lactamase-producing A. baumannii only. Silver resistant strains of A. baumannii produced fl-lactamase. Sensitivity and resistance to copper and cadium was equally distributed between ~-lactamase producers and non-producers, fl-Lactamase-producer and -non-producer strains were uniformly sensitive to cadmium except Acinetobacter genospecies 1.
