Antibiotic Susceptibility Patterns in Recurrent Urinary Tract Infections Among Young Females
Main Article Content
Abstract
Background: Recurrent urinary tract infections (UTIs) are a frequent cause of healthcare visits among young females and are increasingly complicated by antibiotic resistance. Objective: This study aims to investigate the bacterial distribution and antibiotic susceptibility patterns among young females with recurrent UTIs in Khulna, Bangladesh. Methods: A cross-sectional study was conducted among 106 young female patients aged 18–35 years, diagnosed with recurrent UTIs at Khulna City Medical College from January to March 2025. Data on antibiotic intake history, treatment adherence, and urine culture results were collected. Antibiotic susceptibility testing was performed using standard laboratory protocols. Results: The majority of patients (36.8%) were between 23 and 27 years old. About 29.2% of participants reported antibiotic use more than three times in the past year. Only 41.5% consistently completed their prescribed antibiotic courses. Escherichia coli was the most common isolate (69.8%), followed by Klebsiella pneumoniae (17.0%). Both E. coli and Klebsiella showed the highest sensitivity to Imipenem and Meropenem (100% for K. pneumoniae; 64.9% for E. coli). Ampicillin exhibited the lowest sensitivity, particularly against Klebsiella (0%). Conclusion: The study demonstrates a high prevalence of recurrent UTIs caused by multidrug-resistant uropathogens, driven in part by incomplete antibiotic courses. Regular surveillance and patient education on antibiotic adherence are essential for reducing UTI recurrence and antibiotic resistance.
