The study's goal is to determine the incidence of bacteria from urinary tract infections and their antibiotic susceptibility patterns (UTIs). From 2015 to 2017, Shiraz University Laboratory performed a retrospective examination of urinary pathogens and their antibiotic susceptibility on urine cultures. Antimicrobial susceptibility testing was performed according to CSLI standards, utilizing the disk-diffusion technique. 3489 samples were culture positive during the course of the two-year investigation. The most common isolate was Escherichia coli (84%) followed by Klebsiella sp. (10.7%) and Enterococci sp. (22%). Trimethoprim-sulfamethoxazole, ceftriaxone, and ciprofloxacin resistance rates were 56.1 percent, 47.2 percent, and 37 percent, respectively. E. coli was the most often isolated bacterium, with resistance rates of 58.6%, 49.1% to TMP-STX, and cefixime, as well as nitrofurantoin sensitivity rates of 95.1 percent (FM). Resistance to fluoroquinolones and cephalosporin was common in the research region. Because most isolates were responsive to FM and aminoglycoside, these antimicrobials are recommended for empirical therapy of UTIs until urine culture findings are available.
