Background & Objectives: Diabetes mellitus is increasingly recognized as a major health concern worldwide, particularly in developing countries like India. Diabetic individuals are known to have a higher susceptibility to urinary tract infections (UTIs), compounded by the emergence of drug-resistant uropathogens. This study aims to determine the prevalence and etiology of UTIs in diabetic patients. Materials and Methods: A cross-sectional prospective study involving 220 individuals was conducted from March to April 2023 to assess the spectrum of pathogens causing UTIs and their antibiotic susceptibility. Primary cultures were performed on McConkey agar and sheep blood agar, followed by identification and antimicrobial susceptibility testing (AST) using the Vitek2 system and Kirby Bauer's disc diffusion method on Mueller-Hinton agar. Results: Of the 220 samples tested, 150 exhibited significant bacteriuria, with 36 (75%) of 48 diabetic individuals testing positive for UTIs. Gram-negative bacilli (GNB) accounted for 135 (61.4%) isolates, with Escherichia coli (E. coli) being the most prevalent pathogen (52.7%), followed by Klebsiella spp. (25.3%). Among gram-positive organisms, Enterococcus spp. (5.3%) were predominant, with Candida isolates detected in 3 cases (2%). Meropenem (87.6%) exhibited the highest susceptibility against GNB, followed by Netilmycin (87.6%) and Imipenem (82.5%). For gram-positive organisms, Imipenem and Nitrofurantoin demonstrated high susceptibility. Conclusion: E. coli emerged as the predominant pathogen in both diabetic and non-diabetic populations. High sensitivity to meropenem, imipenem, amikacin, and fosfomycin was observed in both groups, suggesting their potential for empirical treatment. Regular surveillance of drug resistance patterns is crucial for identifying evolving resistance trends and optimizing treatment strategies.
