The effect of two types of intestinal bacterial normal floral (E.coli and klebsiella) were tested against 50 bacterial isolates collected from different infection of patients and hospital setting ,using inverted disk technique and wells on nutrient agar, the result revealed that the normal flora were affected on 30 bacterial isolates from total 50 isolates .The effect of normal flora were appear on 8 isolates from burns and wounds,5 isolates from ear infections, 9 isolates from gastrointestinal
