The effect of Quercus infectoria and Citrus auranifolia on klebsilla pneumonia and Escherichia.coli isolated from children suffering from diarrhea

Abstract

The aim of this study was to investigate the effect of watery and alcoholic extract for Quercus infectoria and Citrus auranifolia on growing of Escherichia coli and Klebsilla pneumonia which isolated from diarrhea cases in children .All the extracts have inhibitory effect on tested bacteria .The watery extract of Quercus infectoria had the greatest inhibitory effect , it was 29± 0.33 , 27±0.57 mm with standard error in the concentration 100 mg/ml on both bacteria Escherichia coli and Klebsilla pneumonia, followed by the alcoholic extract of Citrus auranifolia in which it make it inhibitory zone was 24.6 ±0.33 mm with standard error in concentration 100mg/ml on the Klebsilla pneumonia.The statically results shows that the watery extract of Quercus infectoria had more inhibitory effect comparing with the alcoholic extract . The alcoholic extract of Citrus auranifolia inhibited the growth of both types of bacteria more than the watery extract .
