The aim studywas carried out to determine the potentialantibacterial effect of ethanol extract of Camellia sinensis L against E. coli. All 30 strains of E.coli isolated from urine culture of hospitalized patients Hospital( Zabol, south-eastern Iran) suffered from urinary tract infections during the years 2011- 2012 and the minimum inhibitory concentrations were investigated by microdulition method. The result show that the resistant antibiotics against the isolates were nalidixic acid (41.17%), ceftazidime (41.17%) and ampicillin (58.92%). To determine the lowest concentration that completely inhibited visible growth, the minimum inhibitory concentration (MIC) was used. The MIC of Camellia sinensis against E. coli were shown in Table 1, showing that the highest MIC of Camellia sinensis against E. coli was 10mg/ml.
