Abstract
To assess the change in the bacterial profile and pattern of antibiotic resistance of catheter associated urinary tract infections (CAUTIs, the most prevalent form of nosocomial infections) in hospital environment. Susceptibility pattern was done by disk diffusion method. All the isolated organisms were put into appropriate media for antibiotic susceptibility test by Kirby-Bauer disc diffusion technique. All the bacterial isolates of CUTI were 100% sensitive to Imipenem. E. coli were found to be 60.6% sensitive to Nitrofurantoin, 57.6% to Gentamicin, 45.4% to Ceftriaxone and 42.4% to Azithromycin whereas in other antibiotics, the percentages of sensitivity were less. The sensitivity patterns of Klebsiella spp. were found 100% to Gentamicin, 66.7% to Nitrofurantoin and Ceftazidime each. Moreover, this study concludes that E. coli and other isolates were more sensitive to Imipenem, Gentamicin and Nitrofurantoin compared to other antibiotics tested and therefore these may be the drugs of choice for the treatment of Gram negative isolates of Cathereter associated UTIs in our region.
