Staphylococcus aureus infections are an important cause of skin, soft tissue and invasive infections that are acquired in hospitals or community. Nowadays antibiotics play important role for treating bacterial infections, but due to the increasing resistance of bacteria and their side effects, the use of plant extracts as alternative treatment being used. Antibacterial affects different types of tea have been proven, synergistic effects of tea have also been reported with antibiotics. The aim of this study was to evaluate the inhibitory effect of black tea extract on Staphylococcus aureus compared with the standard antibiotic. In this study, black tea extract was prepared by using the percolation method. Bacteria were tested by antibiogram test with standard antibiotic discs containing ciprofloxacin, cefazolin and vancomycin. Data were analyzed using statistical tests and analysis of variance. The results were obtained from this study showed that black tea extract on the growth of Staphylococcus aureus inhibitory is dose-dependent 100 mg/ml has the maximum inhibitory effect.
