Abstract: According to increased bacterial resistance to common antibiotics, tendency toward using herbal drugs is increasing. Many researches have been executed about antibacterial and preservative effects of herbal extract like extracts of lamiacceae family (like Shiraz oregano herb). In this study, anti microbial effects of Zataria multiflora extract on Urinary Tract E. coli Infections in comparison with eleven antibiotic disks in antibiogram pattern is evaluated. After providing microbe suspension and comparing it to Mc Farland 0.5 to obtain 1.5x108 bacterium per milliliter the susceptibility of the mentioned bacteria was determined in Muller-Hinton agar by embedding the disks of Betadine, Zataria multiflora and antibiotic disks. Fallowing incubation of media for 24 h at 37°C the inhibition zone of Zataria, Betadine and antibiotic disks were measured. Surprisingly, according to antibiogram results, the most sensitivity of E. coli was to Z. multiflora extract and inhibitory zone produced by eleven antibiotic disks and betadine are significantly less than Zataria induced. According to obtained results and limitations of increasingly usage of chemical antimicrobial substances there is a need to replacement of these substances with natural and herbal extracts.
