Frequency and microbiological profile of urinary tract infections in patients with indwelling catheters at Bacteriology Laboratory of Centre Muraz

Frequency and microbiology of urinary catheter infections

Abstract

Urinary tract infection is a major risk for people with urinary catheters. The risk and profile of the microorganisms
involved can be influenced by poor hygiene in healthcare facilities as well as in the patient's home. The purpose of
the present study was to determine the frequency and the profile of urinary tract infections etiological agents in
patients with indwelling catheters, requesting Cytobacteriological Examination of the Urine at the Bacteriology
Laboratory of Centre Muraz.
A total of 47 patients were enrolled in this study between June 01, 2020 and September 16, 2021. Among these, the
sex-ratio was equal to 14.67 or 44 male and the average age was 66.91 with extremes of 25 years and 98 years. This
study highlighted the fact that enterobacteria (in particular E. coli and K. pneumoniae) represent the major etiological
agents of urinary tract infections in patients with indwelling catheters, with significant drug resistance cases
associated to Ceftriaxone, Amoxicillin-Clavulanate and Norfloxacin.

These results highlight the high risk of urinary tract infection in indwelling tube carriers, especially in elderly male
patients. This risk also seems to be associated with antibiotic resistance and requires a strengthening of hygiene for
its reduction but also for a quality diagnosis.
