Catheter-related urinary tract infection (UTI) remains a leading cause of nosocomial infections, with significant morbidity, mortality and additional hospital cost. Bacteria isolated from CAUTI are more resistant to antimicrobials compared with community acquired ones. To find out the various bacteria and their antibiotic sensitivity pattern causing the catheter associated urinary tract infection. This was a cross sectional study. Total 200 urinary samples of those patients were taken in study that developed CAUTI after 48 hours of Catheterization. Microorganisms isolated were identified according to colonial morphology, gram-stain reaction and standard microbiological procedures. Antibiotic sensitivity testing of isolated organism was done by Kirby-Bauer disc diffusion method. Out of 200 urine samples, 64 samples were found culture positive. Overall incidence rate of CAUTI was 32%. The most common bacteria isolated was Escherichia coli (40.06%) and second most common isolate was Klebsiella species (21.8%). E.Coli (84%) and Klebsiella (28%) have maximum sensitivity to nitro furantoin, followed by levofloxacin and ampicillin-salbactum. Pseudomonas was resistant to all antibiotics. Acinetobacter was also resistant to almost all antibiotics except levofloxacin and Nitrofurantoin in which sensitivity was only 25%. Both S. aureus and Enterococci are 100% sensitive to Linezolid. In present study we found that mostly all isolates were resistant to almost all primary antibiotics and demands for further antibiotic susceptibility testing with higher antibiotics. The duration and aseptic precautions taken during catheterization can affect the incidence of CAUTI. Continuous monitoring and training of staff is required to ensure that the preventive practices are meticulously undertaken.
