Özet

Objective: This research aims to characterize extended-spectrum beta-lactamase (ESBL) producers and assess the antimicrobial susceptibility patterns of Enterobacteriaceae isolated from clinical care patients in the Aksaray province, Turkey, spanning from January 2017 to December 2021. Material and Methods: Clinical strains will be microbiologically isolated and identified. Antibiotic resistance profiles of Enterobacteriaceae isolates will be determined, and the presence of the blaCTX-M gene will be investigated using molecular methods. Results: Initially, 1752 clinical strains were isolated and identified using VITEK® 2 with an automated ID and susceptibility system. Subsequently, identified and suspected isolates were subjected to PCR for blaCTX-M gene detection. Klebsiella pneumoniae (43.95%) was more common than other species, including Escherichia coli (45.89%). Antimicrobial susceptibility revealed resistance percentages of 86.62% to ampicillin, 76.33% to amoxicillin/clavulanic acid, 64.52% to cefuroxime, 59.14% to trimethoprim/sulfamethoxazole, 59.99% to ceftriaxone, 58.35% to ceftazidime, and 54.39% to ciprofloxacin. Fosfomycin, nitrofurantoin, imipenem, and amikacin exhibited sensitivity in 45.49% of urine isolates. ESBL positivity was observed in 47.63% of E. coli and 61.16% of K. pneumoniae isolates. Conclusions: The prevalence of ESBL-producing E. coli was relatively high. Antimicrobial resistance is a complex issue influenced by widespread antibiotic usage. Insights from trend research can contribute to a broader assessment of antibiotic resistance profiles in Turkish provinces.
