Abstract

Bacteria multidrug-resistance (MDR) pathogens led to increasing hospital and community – acquired infections, for which current antibiotic therapies are not effective which represent a growing problem, its well-known that the silver ion and silver nanoparticles have strong effect against microbial. In this study we prepare silver Np in chemical reduction methods and tested it on three types of multidrug resistance bacteria: Proteus mirabilis, Bacillus cereus and Salmonella typhi The result showed that the sliver Np has a strong effect against gram-positive and gram-negative bacteria.

Keywords: Silver Np, antibacterial, Proteus mirabilis, Bacillus cereus, Salmonella typhi.
