In this study, Invitro evaluation of some Iranian plants against Staphylococcus aureus Isolation of Urinary Tract Infection by microtiterplate method. All 12 strains of Staphylococcus aureus isolated from urine culture of hospitalized patients during the years 2012- 2013. Minimum Inhibitory Concentration (MIC) of plant extract and essential oil against bacteria were determined using micro dilution broth method at six different concentrations. The result showed that the antibiotic susceptibility of S.aureus isolates was evaluated for 6 antimicrobial. Antibiotic susceptibility of S.aureus isolates was evaluated for 6 antimicrobial and more resistance were to oxacillin(83.3%), ceftazidime(66.6%) and penicillin(50%). Thehighest MIC values of extract were found to be 2.5 mg/ml against S.aureus and one of MIC value for S.aureus was 0.62mg/ml. This study also confirm the antimicrobial potential of investigated plants and their usefulness in treatment of resistance microorganisms gram-positive.
