The present work is aimed mainly to investigate  and compare the antibacterial activities of methanolic, diethyl ether and ethyl acetate extracts of retama on Escherichia coli, Salmonella, Proteus mirabilis and Staphylococcus aureu using well difusion method.The results of study showed a significant effect on all bacterial species except Proteus mirabilis. The preliminary test of retama constituents revealed the presence of active material : Resins, Volatil oils,  Coumarins, Terpenes, Phenols, Tannins, Alkaloids, Saponins, Cardiac glycosides, and Flavons. The highest Inhibition rate of Salmonella is 16 mm  at the concentration 100 mg/ml,  while the lowest inhibition rate was 8 mm  for Escherichia coli  at concentration 1 mg/ ml in methanolic extract. The results obtained in the present study suggest that the retama stalks (broom broom) can be used in treating deseases caused by the tested organisms. Further chemical and pharmacological investigations may be carried out to isolate and identify the chemical constituents in the selected plants responsible for the antimicrobial activity.
