Abstract EN

A bacteriological and morphological studies were conducted in biotechnology department/Alnahreen University, and biology department/college of science for women/Baghdad University, which aimed to identify the effect of alcoholic plant extract ,the MIC was determined 50Mg/ml and studied with two concentration (100 ,150 Mg/ml) on different microorganism(EscZicr£s/*ia coli, Staph.aureus, Klebsiella pneumonia, Salmonella typhi JSacillus subtilus ,Pseudomonous aeurogenosa and Candida albicana .

The concentration 150mg/ml of the alcoholic plant extract was superior with an inhibition zone measuring (20.25,17.80,26.25,20.25,17.15 mm) for (E-coli , S.aureus , pneumoniae Kpneumonia, S.

typhi and P.aeurogenosa) respectively whereas the concentration 100 mg/ml of the alcoholic plant extract was significant for bacteria B.

subtilus and in C.albicana yeast with zone of inhibition (17.15and 17.90mm) respectively compared with negative control.

Also an antimicrobial culture and sensitivity test was studied as a positive control using Tetracyclin and Amoxycillin, the concentration (150mg/ml)of tetracyclin gave the highest zone of inhibition in E-coli , S.aureus and same concentration of amoxicillin gave the highest inhibition zone in S.

typhi, P.aeurogones,while the same concentration of the alcoholic plant extract gave a wider diameter of inhibition zone for the same bacteria compared to the positive control.
