A Pattern of Antibiotic Resistance in Gram-Negative Rods Causing Urinary Tract Infection in Adults
Abstract
Background and aim Gram-negative rods (GNR) are the most common pathogens associated with urinary tract infections (UTI). The resistance of these gram-negative rods to various antibiotics is increasing with time. The study aimed to determine the pattern of resistance to antibiotics in GNR causing urinary tract infection in adults. Material and methods This is a cross-sectional study conducted during six months (1st December 2019 to 1st June 2020) among adult patients admitted to Russells Hall Hospital Dudley, UK. Urine cultures of 156 patients admitted with urinary tract infection were collected and reviewed. Sources of urine included midstream urine (MSU), catheter specimen urine (CSU), and others from nephrostomy bags and urine bags. Sensitivity and resistance were checked using Clinical and Laboratory Standards Institute (CLSI) guidelines. Results were analyzed using SPSS version 13. Results Altogether 156 patients were included in the study. Males were 40.4% of the patients were males, and 59.6% were females. The mean age was 78 with a standard deviation (SD) of 13.15. Most of the samples (67.3%) were urine MSU, 23.1% catheter urine, and 9.6% were others, like from nephrostomy bags or unspecified. Resistance to amoxicillin was found in 61.7%, trimethoprim in 36.2%, nitrofurantoin in 13.2%, ciprofloxacin in 25.6%, fosfomycin in 10.7%, co-amoxiclav in 36.2%, gentamicin in 12.8%, piperacillin-tazobactam in 7.1%, cephalexin in 44.4%, and meropenem in 0% of patients.…
