| The antibacterial effect of ethanol and aqueous extracts of Zea mays L and Urtica dioica L, was investigated on bacteria were obtaind from human Urinary Tract Infection (UTI) from Hawlery Ferkary Hospital in Erbil City- Iraq. ,by using the well diffusion technique .A total of 120 isolates bacterial isolates were from 180 UTI patient, isolates were identified as E.coli, Staph. albus, Staph .capitis, Staph epidermidis , Staph. aureus, Pseudo luteola, Pseudo.aeruginosa, P. mirabilis, Morganella.Morganii, K. Pneumonia, K. oxytoca, Micrococcus and Citrobacter freundii following different morphological , physiological and biochemical test. Antibiotic sensitivity of17 commerical antibiotic discs AK, AMC, AMP, AT, ATM, AZM, CAZ, CD, CEP, CFM , CIP, COT, CRO, GM, IPM, MEM and NA was screened by disc diffusion assay , It was observed that the extracts of both plant had an inhibitory effect on the bacteria under study , except Pseudo luteola to extracts of Zea mays L and Pseudo luteola, K. Pneumonia and K. oxytoca to extracts of urtica dioica L. The inhibitory concentration of Zea mays L. extracts was 75% and 100% and urtica dioica L extracts was 50%, 75% and 100%. The antibacterial activity of extracts of U.dioica showed the best action as inhibitor against test bacteria than the extracts of zea mays. The result showed that there is an antibacterial activity of alcoholic extract of U.dioica higher sensitivity when compared with standard antibiotics. |
