The aim of this study was to evaluate the effect of walnut tree root (Juglandaceae) on Escherichia coli is resistant to various antibiotics. Walnut tree root extract was obtained using a rotary device. 20 cases of E. coli was obtained from urinary tract infections Zabul hospital and MIC and MBC were determined using dilution in the wells. The results of the study showed that the concentrations of 20 and 10 mg L had the highest inhibitory effect at a concentration of 40 milligrams per milliliter, most have lethal effects. Our results suggest the effect of the extract against the tested bacteria in the laboratory that can represent their effects on living systems.
