Objective: The research was carried out with isolate and determines the antimicrobial sensitivity in E. coli from urinary tract infections in special hospital in Denizli and recorded at specimens. Methods: Urine samples (n=21) were collected from patients with signs and symptoms of Urinary tract infections. Bacteria were isolated and identified by conventional biochemical profile. Antibiotic resistance pattern of E. coli against different antibiotic was determined by Kirby-Baur method. Results: The results revealed that sensitivity rate of antimicrobial agents were in the range of meropenem (100%), norfloxacin and ciprofloxacin (86%), cefotaxime (80%), aztreonam (76%). None of the samples showed no resistance to amikacin, ceftazidime, aztreonam, amoxicillin/clavulanic acid, and meropenem. Out of 21 isolates, 3(14%) isolates showed Multiple Antibiotic Resistance ten to thirteen antibiotics. Conclusion: It is concluded that most of the urinary tract infections in human are caused by E.coli exhibited highest resistance to meropenem (100%), followed by norfloxacin and ciprofloxacin (86%).We aimed in these research to determine the status of antibiotic resistance, underlying conditions, and isolation of E.coli isolates with from a special hospital in Denizli, Turkey.

Background: Pseudomonas aeruginosa is an important hospital infection agent causing morbidity and mortality with the ability to gain resistance to many antimicrobials. The objective of this study was to determine the sensitivity profiles of nosocomial P.aeruginosa isolates in Denizli, Turkey.Methods: A total 120 P. aeruginosa strains which were isolated from specimens sent to the microbiology laboratory between January 2015 and December 2015 were investigated. Antimicrobial resistance was determined by agar disc diffusion method using Mueller-Hinton agar according to Clinical and Laboratory Standards Institute recommendations.Results: With respect to sensitivity pattern, the most sensitive antimicrobials were  Amikacin, colistin, tobramisin, netilmicin and gentamicin  and the resistance rates were detected as 97%, 96%, 92%, 90%, 83%, respectively over 120 P. aeruginosa strains. The sensitivity rates for the other antimicrobials were 56% for Piperacilin and 54% for Tazobactam. P. aeruginosa strains 62 (52%) isolates showed multiple antimicrobial resistance to 13 antimicrobialsConclusion: To prevent the spread of the resistant bacteria, it is critically important to have strict antimicrobial policies while surveillance programmes for multidrug resistant organisms and infection control procedures need to be implemented. In the meantime, it is desirable that the antimicrobial susceptibility pattern of bacterial pathogens like P. aeruginosa in specialized clinical units to be continuously monitored and the results readily made available to clinicians so as to minimize the development of resistance.
