Аннотация
AIM: This study aimed to identify Gram-negative uropathogens (GN-UP)-producing extended-spectrum beta-lactamases (ESBL), metallo-beta-lactamases (MBL), and AmpC enzymes in diabetic patients and to analyze their antibiotic resistance profiles.
MATERIALS AND METHODS: Urine samples were cultured, and isolates were tested using the Kirby-Bauer disc diffusion method.
RESULTS: E. coli (43%) was the most common isolate, followed by Klebsiella spp. (25%). Among GN-UP, 13.26% were ESBL producers, 63.26% MBL producers, and 17.34% AmpC producers. MBL-producing isolates showed lower resistance to fosfomycin (22.58%), tigecycline (32.25%), and nitrofurantoin (33.87%). The high prevalence of MBL, ESBL, and AmpC producers in diabetic urinary tract infection (UTI) patients complicates effective antibiotic therapy.
CONCLUSION: These findings underscore the need for regular antimicrobial surveillance and tailored treatment strategies in this vulnerable group.
