Antibiotics Resistance of Isolated Bacteria from Patients with Urinary Tract Infection

From the period of March to thirty August 2015, 210 urine samples were collected from patients with signs and symptoms of UTIs with an age range of 20-60 years, who referred to outpatient department of AlKarama teaching hospital, Baghdad. Out of 210 samples of urine 150(71.43%) were positive culture and 50(23.81%) were negative culture while 10 (4.76%) were showed contaminated urine culture. The common isolated bacteria were E. coli 45 (30%), K. pneumonia 33(22%)as Gram negative bacteria respectively, while Gram positive bacteria was Staphylococcus aureus 42(28%). The other bacteria were Enterobacter spp.20 (13.3%), Proteus spp. 6(4%), and Pseudomonas aeruginosa4 (2.7%). Susceptibility testing were used with the following antibiotic disks: Ciprofloxacin, Amikacin, Nitrofurantion, Trimethoprim-Sulfamethoxazol, Gentamicin, Pipracillin , Nalidixic acid , Tetracycline , Imipenem , Ceftriaxone , and Cefotaxime. The percentage of susceptibility showed variable susceptibility to the antibiotics used. All bacteria showed (100%) susceptible to Imipenem while all bacteria showed (100%) resistant to Tetracycline. Pseudomonas aeruginosa isolated bacteria was showed multidrug resistant (MDR); seven antibiotics: Nitrofurantion, Trimethoprim-Sulfamethoxazol, Pipracillin, Nalidixic acid, Tetracycline, Ceftriaxone and Cefotaxime.
