Antibacterial effects of silver nanoparticles on the bacterial strains isolated from catheterized urinary tract infection cases.

Urinary tract infections (UTI) are among the most common type of nosocomial infections. Patients with indwelling urinary catheters are at the highest risk of getting infected. The antibacterial effects of silver compounds have been known to man kind for ancient times. It has recently been found that silver nanoparticles possess significant antibacterial potential. Surface modifications of urinary catheters with Ag-NPs may prevent the risk of contamination and the associated infections. In this study we have studied the antibacterial effects of Ag-NPS on bacterial isolates from UTI cases. Our results suggest possible utility of Ag-NPs as coating agent.
