Urinary tract infections and their complications causing serious health problems especially in diabetic patients in Misan province, it is essential to determine the causative agent for appropriate treatment of this disease. One hundred and fifty urine samples were taken from adult patients with diabetes. The microbial growth appeared in 106 (70.6%) samples. Axenic culture was 83% versus 17% mixed growth. UTI prevalence was 65% with females comparing 35% of males and it was 56.6% in age group 35-49 years. Furthermore, UTIs were more incident in patients without antibiotics use and diabetic period 5-10 years (82% and 64%) respectively. Escherichia coli was identified as the most common causative agent of UTIs (52.9%), followed by Klebsiella pneumoniae and Enterococcus faecalis (9,1% and 6.6%, respectively). Streptococcus agalactiae and Klebsiella aerugenes were (4.2%, for each). Moreover, Pseudomonas aeruginosa, Klebsiella oxytoca and Staphylococcus haemolyticus were 2.48% for each. Additionally, the frequency of Proteus mirablis, Staphylococcus aureus, Streptococcus pyogenes, Serratia marcessens, Staphylococcus epidermidis and Staphylococcus warnerii was 1.65% for each, while Acinetobacter baumani and Bacillus subtilis were 0.82% for each. Most bacterial isolates had a high sensitivity to imipenem (78.8%) followed by amikacin (61.9%), but low sensitivity to ceftriaxone, tetracycline and Co-trimaxazole (36.4%, 29.7% and 26.3%, respectively) whereas, highly resistance to ampiclox and nitrofurantoin (98.3% and 87.3%, respectively). High rate of multidrug resistance observed among bacterial isolates.
