摘要：By increase of people information about synthetic antibiotic dangerous effects, the demands for natural replacement of these drugs have increased. This study is done by the purpose of synergistic specification of Nano silvers and turnip extract on pathologic bacteria. In this study the turnip plant was used by scientific name of Brassica Napus L. and silver Nano particles. The alcoholic extract of plant is taken first and then concentrations of 50, 100, 200, 400 mg/ml were evaluated. In the last phase the above concentrations were combined together and used for selected bacteria. All tests procedures published by the Well Diffusion Agar, Disk Diffusion Agar and the MIC/MBC on S. aureus, B. cereus, E. coli and P. aeruginosa was performed. The results showed that silver Nano particles comparing to turnip plant alcoholic extract has more antibacterial effect. The turnip extract had more effect on positive gram bacteria while silver Nano particles had much effect on Gram negative bacteria. The effect of turnip extract was more than each of them as this composition has the most effect on Pseudomonas aeruginosa and the least impact on Staphylococcus aureus. Using this composition has considerable effect on pathologic bacteria growth. In order to use clinical application of this composition, doing clinical researches is essential
