AB  - The multidrug-resistant bacteria Acinetobacter baumannii cause serious hospital infections. Commercial poly(vinyl chloride) (PVC) used for endotracheal tubes was modified in order to obtain a composite with an antibacterial effect towards a clinical isolate of A. baumannii ST145. The composites were prepared by addition of different amounts of copper-containing zeolite tuff (CuZ) and by successive impregnation with D-tyrosine (D-Tyr) solution. The composites that were obtained by addition of CuZ (CuZ PVC) only did not exhibit an antibacterial effect. The impregnation of the CuZ PVC by D-Tyr resulted in an antibacterial effect which was explained by a synergistic effect of CuZ and D-Tyr. Rheological tests confirmed that the modification of PVC by CuZ does not affect its processability and reformability.

AB  - Due to their susceptibility to bacterial biofilm formation, commercial tubes for medical use are one of the main sources of hospital infections with Acinetobacter baumannii. The anti-biofouling activity of novel composites against the clinical isolate of the multi-drug resistant A. baumannii is reported here. The composites were prepared by addition of micronised silver-exchanged natural zeolite (Ag-NZ) into poly(vinyl chloride) (PVC), followed by coating of the composites with D-Tyrosine (D-Tyr). The Ag-NZ composites (containing 1-15 wt% of Ag-NZ) coated with D-Tyr (Ag-NZ-Tyr) showed a bactericidal effect (100% or a 6.9 log CFU reduction) towards immobilised bacterial cells. The uncoated Ag-NZ composites showed a reduction of up to 70% (4.4 log CFU) of immobilised bacteria in comparison with the original PVC. Rheological testing of the composites revealed that the addition of Ag-NZ slightly affected processability and formability of the PVC and increased the elasticity of the polymer matrix.

AB  - The antibacterial activity of natural zeolite (NZ) containing 2.03 wt.% of Cu2+ (CuNZ), 5.07 of Ag+ (AgNZ) or 8.50 of benzalkonium ion (BCNZ) were tested against clinical isolates of Acinetobacter baumannii belonging to European clone I and II. Isolate from clone II was more sensitive to CuNZ and AgNZ with minimum bactericidal concentration (MBC) 125 and 31.2 mg L-1, respectively than isolate from clone I with MBC of 250 mg L-1 for both CuNZ and AgNZ. Isolate from clone I was more sensitive to BCNZ with MBC 250 mg L-1 than isolate from clone II with MBC 500 mg L-1. The minimum inhibitory concentration (MIC) values were the same or slightly lower than the MBC values. The antibacterial activity of CuNZ, AgNZ and BCNZ against the A. baumannii European clone I and II was due to the activity of cations loaded onto NZ while not to the NZ used as support material. The antibacterial activity of CuNZ, AgNZ and BCNZ opens a possibility of future clinical investigations and its application.
