ABSTRACT

It is common phenomenon that microorganisms are developing their resistance to many commercial drugs that is major cause of failure to treat bacteria infection diseases( Davies J. 1994), 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: Streptococcus fecalls, Klebsiella oxytoca, and Shigella flexneri The result showed that the sliver Np has a strong effect against gram-positive and gram-negative bacteria.

Keywords: Silver Np,antibacterial, Streptococcus fecalls, Klebsiella oxytoca, and Shigella flexneri.
