Prevalence of uropathogens in urine and their resistance patterns: data analysis from a single centre

Abstract

Introduction: Antibiotic resistance is a major issues in contemporary health care, including in the speciality of urology. Multi-drug resistant bacteria are now commonplace not just in the hospital environment, but also in the community.

The objective of thiswork was to investigate the prevalence of uropathogens and their resistance patterns in our department. Methods: Data on prevalence and antibiotic resistance of uropathogenic bacteria were extracted from the electronic database for the Department of Urology for the year 2017.

Results: A total of 2036 individual uropathogens were detected between 1st January and 31st December 2017. E. coli was the most common(n = 726, 35.7 %), followed by Enterococcus sp. (n = 495, 24.3 %) and Klebsiella sp. (n = 206, 10.1 %).

A half of E. Coli isolates were ciprofloxacin-resistant and 36 % were co-trimoxazol-resistant.

Klebsiella sp. were markedly resistant to ciprofloxacin (58.4 %), over a quarter were also resistant to amoxicillin-clavulanate, cefalotin, cefuroxime, cefotaxime, ceftazidime, co-trimoxazole, ofloxacin, piperacillin-tazobactam and tetracycline. A total of 155 multi-drug resistant pathogens were detected.

Most of them belonged among extended-spectrum beta-lactamase (ESBL, n = 108) positive Enterobacteriaceae. No gram-negative rod except Pseudomonas aeruginosa proved resistant to meropenem or imipenem.

There was no vancomycin-resistant isolates of S. aureus and Enterococcus sp. detected. Conclusion: Our data on prevalence and resistance of uropathogenic microorganisms are comparable to those from the literature in our geographic area.

They confirm high rates of resistance to many commonly used antimicrobials.
