| Abstract | ||
| Antibacterial activity was detected for alcoholic extraction of Cotoneaster fruit against some pathogenic bacteria included; Escherichia coli, Staphylococcus aureus, Bacillus subtilis, Pseudomonas aeruginosa and Proteus sp. Antibacterial activity of alcohol extract was determined by using the micro dilution method (well diffusion and disc diffusion methods). Alcoholic extract showed a concentration of 200 mg / ml of Cotoneaster fruit highest inhibition zones of pathogenic bacteria for each region compared to concentrations of 50 and 100 mg / ml of the extract. Besides that there is a difference according to the type of bacteria, as shown by inhibition of Proteus sp. area (17.25 ± 0.48)mm compared with Staphylococcus aureus which gave less inhibition of diameter by region (12.75 ± 0.48)mm. Alcoholic extract in well method showed a higher effects against all pathogenic bacteria in used in comparison with disc method , at 50 , and 100 mg /ml, while there does not appear significant difference against the bacteria Escherichia coli; Pseudomonas aeruginosa; and Proteus sp. in concentration of 200 mg / ml. | ||
