The study of bacteriological factors and antibiotic resistance in women with UTI referred to the Razi laboratory in Dezful

The prevalence of urinary tract infection in women is more observed rather than in man and mostly half of women have experienced it in their lifetime. On one hand, understanding the regional prevalence of pathogens and antibiotic resistance of microorganisms to antibiotics is effective to proper selection of antibiotics and infection control. The purpose of this study was to investigate the frequency of urinary tract infections, bacterial factors and antibiotic resistance. This descriptive - cross sectional study was conducted on urine samples from 765 women referred to the Dezful Razi laboratory in 2012. Cultivation, isolation and identification of bacteria were performed using standard bacteriological methods, then the antibiotic resistance in bacteria E.coli was studied using antibiogram tests through agar disk diffusion by Kirby-Bauer method. The number of 765 samples studied, 160 (20.91%) were reported positive. Escherichia coli with 106 cases (66.25%), Klebsiella 33 cases (20.63%), and Staphylococcus six cases (4.38%) were identified as urinary tract infections. Most Escherichia coli resistance was to ampicillin (96.55%) and the least resistance was to nitrofurantoin (11.12%). Discussion & Escherichia Coli is the most common cause of urinary tract infection that is highly resistant to ampicillin. The resistance can be observed in the case of antibiotics that are used more. The emergence of a new antibiotic resistance is an issue that should be taken seriously.
