Antibacterial activity of metal-loaded natural zeolite against clinical isolates of Acinetobacter baumannii

The antibacterial activity of natural zeolite (CLI) containing 2.60 wt.% Cu2+ (Cu-CLI) or 5.07 wt.% Ag+ (Ag-CLI) were tested against clinical isolates of Acinetobacter baumannii. A. baumannii belonging to the European clone I and II were isolated in Split University Hospital, Croatia. The isolate from clone II was more sensitive on the effect of the metal-loaded zeolite than isolate of clone I. The antibacterial activity can be ascribed to the metal ions inside the zeolite lattice since the natural zeolite itself does not show antibacterial activity toward the studied bacterial strains.
