RESUMO
Aims@#Due to the world's direction of alternative medicine and herbal medication, tea leaves have been employed to inhibit certain bacteria that cause urinary tract infections (UTIs). This study aimed to evaluate the effect of green, red and black tea as antibacterial against UTIs in pregnant women and changes in blood pressure and iron level in the blood of their women.@*Methodology and results@#Forty-eight isolates were isolated from 50 women suffering from urinary tract infections, Staphylococcus aureus (18) 37.5%, Escherichia coli (15) 31.25%, Pseudomonas aeruginosa (8) 16.6%, Klebsiella sp. (5) 10.4% and Enterobacter sp. (2) 4.16%. The sensitivity of bacteria to the antibiotics Amikacin, Amoxicillin/Clavulanic, Ampicillin/Sulbactam, Cefixime, Ceftriaxone, Ciprofloxacin, Imipenem, Nitrofurantion, Penicillin and Tetracycline were tested, while E. coli and P. aeruginosa (8), Enterobacter sp. were resistance for Ceftriaxone and Amoxicillin /Clavulanic (100%). While Enterobacter sp. is sensitive to Nitrofurantoin and Imipenem (100%). The ability of the isolates to form biofilms was tested using the Congo red agar method and the micro titrations plate method. The results showed that not all isolates have the ability to produce biofilms and red tea is the most powerful antibacterial under study. Drinking green tea for two weeks regularly in pregnant women who suffer from high blood pressure showed an improvement in blood pressure, as it became normal 118/78 and with the normal iron level in the blood at a rate of hemoglobin = 11.8, while drinking red tea did not change blood pressure measurements in pregnant women with high blood pressure.@*Conclusion, significance and impact of study@#The effect of red tea extract was stronger than other teas used in the study as an antibacterial against urinary tract bacteria. Regular consumed of green tea helps regulate blood pressure, especially for pregnant women who are at risk of hypertension during pregnancy.
