Introduction and aim: Infections caused by antibiotic-resistant strains of Escherichia coli are mainly hospital-based prevalence is increasing in many countries; Hence efforts taken to find new compounds as an alternative to antibiotics. Therefore, this study is done to evaluate the antimicrobial effects of ethanol extract of lavandula stoechas L.. plant on clinical resistant E.coli.
Material and methods: After collecting plants and validate its scientific name by botanists of Agricultural Organization and after drying in shade, extract of lavandula stoechas L. plant , was extracted by vacum distlllation method and different concentrations of the extracts were prepared. Then, the MIC and MBC of the extracts on E.coli strains that isolated from patients, was determined by broth dilution and agar well diffusion..
Results:The results showed that the MIC and MBC of ethanol extract of lavandula stoechas L. plant on E.coli were 6.5 and 13 mg/ml.
Conclusion: The results of this study show that can be taken lavandula stoechas L. plant in herbals groups with antibacterial properties and after evaluating their effects in vivo condition and to identify the active ingredients, as an alternative to synthetic drugs that commonly used to treat infections are used.
