The mean of four replication to inhibition zone around of each well with green tea, were measured The present study detected no inhibition zone at concentration 2.5 mg/ ml and 5mg/ml against Staphylococcus auras and Pseudomonas aeruginosa while inhibition zone at concentration 10mg/ml, 20 mg/ml and 40 mg/ml ) (12mm, 17mm and 21mm) respectively against Pseudomonas aeruginosa; (10mm, 17mm and 22mm) respectively against Staphylococcus auras. Conclusion of this study, the aqueous extraction of green tae high antimicrobial against pathogenic bacterial isolates.
