Investigation objective was to evaluate the antibacterial effectiveness of various extracts of Thymus vulgaris on two species of bacteria namely Escherichia coli and Staphylococcus aureus, which has been isolated from patients with urinary tract infection. Qualitative detection was carried to detect some effective chemical compounds in all extracts. It was found that extracts contained phenols, flavonoids, tannins, proteins and carbohydrate. All extracts in concentration 150 mg.ml-1 showed inhibitory effect against urinary tract bacterial isolates with varying inhibition diameters. Hot water extract (150mg.ml-1) showed the highest inhibitory effect on both bacterial isolates of Escherichia coli and Staphylococcus aureus in 23 mm and 18 mm diameters, respectively.
