In this study, antimicrobial resistance profiles were determined for 748 isolates of Escherichia coli from patients with acute nosocomial urinary tract infections (UTIs) at a Turkish Training Hospital. Thirteen antibiotics were included. Resistance to ampicillin alone (45.1%) and ciprofloxacin alone (20.6%) were the most commonly identified ‘single resistances’. Multiple resistance was found in 49.7% of the strains. The most common multiple antibiotic resistance profiles included ampicillin-sulbactam/amoxycilline-clavulonate (4.0%) and ampicillin-sulbactam/trimethoprim-sulfamethoxazole/amoxycilline-clavulonate (2.8%). From 2004 to 2006, ampicillin, trimethoprim-sulfamethoxazole and ciprofloxacin resistant strains increased to 76% from 57%, 53% from 43% and 55% from 41%, respectively. The percentage of extended-spectrum β-lactamase (ESBL) producing strains was 7.8% and imipenem resistance was seen in 5.2% of ESBL positive strains. We conclude that clinically important E.coli strains have now emerged with broader multidrug resistance. Periodical evaluation of laboratory results and clinical surveillance are crucially important for optimal antibiotic management of UTIs and infection control policies.

In geriatric practice, data regarding infections including the epidemiology, morbidity, and mortality are lacking. Our aim was to evaluate the frequency, location, microbiological and laboratory characteristics of infectious diseases in elderly population admitted to a training hospital. The patients were included total of 330 patients, aged over 65 with infection, seen between January 1, 2005 and January 1, 2006. In the result, of patients 136 (41%) had respiratory system infection, 90 (27%) urinary system infection, 39 (12%) gastrointestinal system infection, 34 (10%) bloodstream infections, 17 (5%) soft tissue infection, 8 (2%) central nervous system infections, and 6 (2%) others. Average length of hospitalization was 8.6±7.7 days. Mortality rate from all causes was 57 (17%). The most common infections in elderly patients were respiratory tract and urinary system infections, and there were no fever, leukocytes and high CRP levels in approximately 1/3 of cases. Infectious diseases may occur even in the absence of such infection indicators as fever, raised WBC count and high CRP level in the elderly population.
