ABSTRACT: Urinary tract infections (UTIs) are the second most common type of infection found in any organ system, and the most common type of nosocomial infection. The strains of Escherichia coli that infect the urinary tract are categorized as uropathogenic E. coli. The antimicrobial agents that have traditionally been used to treat UTIs (β-lactams, fluoroquinolones, trimethoprim-sulfamethoxazole, nitrofurantoin, etc.) are becoming less effective, According to the reports of many researchers, antibacterial resistance is a worldwide growing problem. Cephalosporin's are useful for UTI's which do not respond to other drugs, can cause side effects that may be serious or even cause death.
Green tea is derived from non-fermented leaves of the Camellia Sinensis plant, Green tea has been a favored drink, traditionally, in Asian countries. Because of studies that have shown the potential health benefits of green tea. A study found that citrus juices enable more of green tea's unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.
The bacteria strains use in this study are part of a research collection of E. coli isolate from UTI cultures during the year of 2016. A total of 10 E. coli isolates are collect from urine specimens submit of selected Al- Hussein medical city patients during one month period throughout November 2015. The isolates are further processes by standard methods to identify as E. coli isolates. This method included the morphological properties and biochemical tests.
The aqueous and alcoholic extracts were prepared by Ahmed's method then the filtered extracts poured in clean and sterile petri dishes and let to dry in the oven for two 2-3 days at a temperature 45-50 C", The concentrations (25,50,75,90,100) % were prepared from the stuck for each aqueous and alcoholic for the green tea and green tea with lemon extracts.
The results showed that the best antimicrobial activity found in concentration of 90% aqueous green tea and at 90% of alcoholic green tea with lemon.
