Extended spectrum β-lactamase and antibiotic suspectibility of escherichia coli grown in urinary isolates [İdrar örneklerinde üretilen Escherichia coli suşlarında genişlemiş spektrumlu beta-laktamaz varlığı ve antibiyotik duyarlılıkları]

Abstract

In recent years, Extended Spectrum ß-Lactamase (ESBL) ra­tes in Escherichia coli which is the causative agent of urinary tract infections, are increasing. In our study, we found ESBL positivity with female and male patients as 9,4 % and 24,3 % respectively. ESBL rate was detected as 9,7% for patients under the age of 65 and 17,8 % for those 65 years and older. These ESBL rates were statistically significant higher in patients over 65 years of age and male sex. The highest antibiotic suscepti­bility rates of ESBL-positive strains belonged to carbapenems (meropenem 99.7 %, imipenem 99.3% and ertapenem 97.3 %). In patients who were admitted to the clinic with complaints of urinary tract infections, the choice of antibiotics taking ESBL risk factors into consideration will increase the success of tre­atment. © 2014, Logos Medical Publishing.
