Investigation of some bacterial causes of urinary tract infection in diabetic patients in Al-Muthanna Province

Background. Urinary tract infections (UTIs) are among the most common infections affecting diabetic patients, contributing to increased morbidity and healthcare burden. This study purposed to investigate the prevalence and bacterial causes of UTIs among diabetic patients in Al-Muthanna Province, Iraq, and to determine the antimicrobial susceptibility patterns of the isolated pathogens. Materials and methods. A total of 200 urine samples were collected from diabetic patients presenting with UTI symptoms. Bacterial identification and antibiotic susceptibility testing were conducted using standard microbiological methods. Results. The results showed that 123 (61.5 %) samples were positive for bacterial growth. Escherichia coli was the most prevalent organism (52 %), followed by Klebsiella pneumoniae (19.5 %), Staphylococcus aureus (13 %), Proteus mirabilis (8 %), and Pseudomonas aeruginosa (6.5 %). High resistance was observed against ampicillin and TMP-SMX, while nitrofurantoin and imipenem showed the highest sensitivity. Conclusions. These findings underscore the need for continuous surveillance and appropriate empirical therapy to manage UTIs in diabetic individuals.
