Abstract

Among nosocomial infections catheter associated urinary tract infection (CAUTI) is one of the most common infection. The antibiotic resistance amongst the uropathogens isolated from CAUTI are multi-drug resistant and a growing public health problem in the world including Bangladesh. The study objective was to determine the aetiology of uropathogens in catheter associated urinary tract infection and find out their anti-microbial sensitivity pattern among the isolates. A cross sectional study was done from July 2016 to June 2017 in Dhaka Medical College, Bangladesh. Urine samples were collected from 400 patients with suspected CAUTI which were processed microbiologically and antimicrobial sensitivity was performed. Out of 400 patients Escherichia coli (38.93%) was the most common isolated organism followed by Pseudomonas spp, (15.98%), Klebsiella spp, (8.61%), Proteus spp. (7.38%) Enterobacter spp, (6.56%) and Acinitobacter spp. (1.22%). Among the Gram positive isolates Staphylococcus aureus (1.64%) and Coagulase negative Staphylococeus (6.97%%) were isolated. Enterobacteriaceae showed high resistant to commonly used antimicrobials Amoxiclav, Gentamycin, Ceftriaxone, azithromycin , ciprofloxacin, cortimoxazole and were sensitive to colistin ,nitrofurantoin ,imepenem, Meropenem. Many isolates showed multi- drug resistance pattern hence strict aseptic precaution has to be taken prior to catheter insertion and after to prevent infection.
