The aim study antibacterial effects of silver nanoparticles against resistant strains of E.coli bacteria.12 strains of E. coli strains arising urinary infection were isolated from hospitalized patient in zabolhospitals. Minimum inhibitory concentration of winter cherry were determined by dilution method in various concentration on bacteria. The highest MIC values was found to be 100ppm against one E.coli and the least MIC values was observed in 12.5 ppm. This work, integrates nanotechnology and bacteriology, leading to possible advances in the formulation of new types of bactericides.
