Sažetak
The antibacterial activity of modified natural zeolites (MNZs) containing (in wt%): 2.60 of Cu2+ (CuNZ), 0.52 of Ni2+ (NiNZ), 1.47 of Zn2+ (ZnNZ), 8.50 of benzalkonium ion - BC (BCNZ) or 8.50 of benzalkonium ion and 1.90 of acetylsalicylic acid - AS (BCASNZ) were tested against pathogenic bacteria: Acinetobacter baumannii belonging to the EU clone I and II, Escherichia coli and Staphylococcus aureus. The CuNZ, BCNZ and BCASNZ showed the bactericidal activity (100% of antibacterial activity) against both clones of A. baumannii. The BCNZ and BCASNZ showed the bactericidal activity against E. coli and S. aureus. For NiNZ and ZnNZ a slight antibacterial activity was found. The bactericidal activity of CuNZ, BCNZ and BCASNZ was due to the activity of Cu or BC cations loaded onto NZ and not to NZ itself. Among all tested MNZs, the BCNZ is a promising material for the control of pathogenic bacteria.
