Total (157) urine samples were collected from renal failure patients undergoing hemodialysis were evaluated in Center of Dialysis unit\ Kirkuk General Hospital in Kirkuk city, including 40 samples from General Population as control group samples. Gram-negative bacteria were isolated in 37(53.62%) of 69 cases with Escherichia coli 27(39.13%), Klebsiella pneumoniae and Proteusmirabilis 3(4.35 %), Pseudomonas aeroginosa 2(2.90 %), 1(1.45%) for both of Citrobacter freundii and Citrobacter koseri. while Gram positive 32(46.38%) in 69 were isolated, Staphylococcus saprophuticus 17(24.63%), Staphylococcus aureus 10(14.49%), Enterococcusfaecalis 3(4.35%) and Staphylococcu sepidermidis 2(2.90 %). The present study was aimed to identify antimicrobial activity of corn silk extract by different solvents (ethanol and chloroform) extracts (100, 50, 25, 12.5, 6.25 mg/ml each).All the extracts showed variable degree of inhibitory effect by using Agar well-diffusion method against tested bacteria. Ethanol extract showed significant antimicrobial activity against in both Gram positive bacteria and Gram negative bacteria the highest inhibition zone (15-30 mm) was observed in 100 mg/ml of ethanolic extract. In antibiotic sensitivity patterns of the isolated bacteria, both Gram positive and negative bacteria were found to be sensitive 100% towards imipeneme and showed resistance to another antibiotics used.
