Prevalence and Risk Factors of Urinary Tract Infections Caused by Multidrug-Resistant Enterobacteriaceae in Nasiriyah, Iraq

Background: Any area of the urinary system—the kidneys, ureters, bladder, or urethra—is susceptible to infection when a UTI occurs. The urethra and bladder are the most common sites of infection in the lower urinary tract. When microorganisms including bacteria, viruses, fungi, and parasites evolve to resist antibiotics, a phenomenon known as antimicrobial resistance (AMR) happens. This makes infections more difficult to cure and raises the likelihood of disease transmission, serious illness, and death. The researchers in this study set out to quantify the prevalence of urinary tract infections (UTIs) in Iraqi residents and to determine which bacterial strains were resistant to antibiotics. Methods: The study included 100 patients who were classified into 75 that were diagnosed with UTI patients, their ages ranged between (16) to (67) years, (45) females and (30) males. In addition to 25 uninfected individuals as controls, their ages ranged between (15) to (59) years, (15) females and (10) males. All participants in the study underwent identical laboratory tests to diagnose UTIs, identify the types of bacterial isolates, and determine their antibiotic resistance patterns Results: The result of the present study shows that E.coli, Klebsiella pneumonia and pseudomonas aeruginosa were the most common types of UTI-associated bacteria with the percentage of 44.71%, 38.57% and 15.71% respectively. Conclusion: pseudomonas aeruginosa had been developed its resistance to several antibiotics and had great predisposition to be MDR.
