الملخص EN

This study was concluded to test the inhibition effect of hot aqueous extract for leaves of Nerium oleander L.

on the growth of the bacteria Klebsiella pneumonia and Escherichia coli which was the bacteria E.coli more effected by the hot aqueose extract with an inhibition diameter 20mm in the concentration of 300mg/ml and 13mm in 150mg/ml while the inhibition diameter was 18mm for the bacteria Klebsiella pneumonia in the concentration 300mg/ml and 14.5mm in concentration 150mg/ml and noted that the mean of inhibition diameter increased with increasing the concentration of the extract .

The study was showed that the possibility usefulness of this extract like operative factor against the diseases that caused by this bacteria or any medical bacteria that because this plant contain compounds which could kill causes of diseases.
