Distribution of community-acquired gram negative microorganisms detected in urine samples of pediatric patients and antibiotic resistance patterns at 2013
Journal Title: Dicle Tıp Dergisi - Year 2015, Vol 42, Issue 2
Abstract
Objective: This study aims to determine the antibiotic susceptibility and distribution of community-acquired microorganisms obtained from urine samples of patients admitted to our clinic in Diyarbakır, and also detect the ratio of extended spectrum beta-lactamase producing E.coli and Klebsiella strains in urine samples, and identify the antibiotics that can be used for the empiric treatment by investigating the susceptibility of extended spectrum beta-lactamase positive strains. Methods: Patients admitted to the pediatric polyclinic of our hospital between the dates 1 January-31 December were included in the study. 1167 urine samples sent to Microbiology Laboratory were examined. E.coli and Klebsiella spp. strains isolated from the urine cultures were identified with traditional methods and the Biomerium Vitek-2 compact system. Antibiotic susceptibility tests were performed in accordance with the recommendations of Clinical and Laboratory Standards Institute using Biomerium Vitek-2 compact system. Results: 959 E.coli from 1167 urine samples and other microorganisms from 26 of 182 Klebsiella spp. were isolated. Extended spectrum beta-lactamase production was detected in 445 (46.4%) of E.coli strains and in 72 (39.5%) of Klebsiella spp.strains. Amicasin resistance was determined as 9.4% in Extended spectrum beta-lactamase positive E.coli strains, while amicasin resistance was detected as 11% in Extended spectrum beta-lactamase positive Klebsiella spp. strains. Conclusion: Resistance development against the antibiotics has been increasingly observed in most of the microorganisms that cause urinary tract infection. We are in the opinion that this study is important for our hospital, as urinary tract infection factors vary according to centers. Key words: Antibiotic resistance, community acquired urinary tract infection, child
