Antimicrobial profile of urinary tract infections at a tertiary care teaching hospital of Central India

Abstract

Background & Aims: Urinary tract infections (UTI) are a leading cause of bacterial infections in humans.The widespread use of antibiotics has resulted in the emergence of antibiotic-resistant microorganisms. Hence, the current study was conducted to investigate the antibiotic sensitivity pattern of uropathogens in UTI. Materials & Methods: A total of 642 urine samples were collected from suspected UTI patients and tested microbiologically. Antimicrobial susceptibility tests were performed for the isolated pathogens using the Kirby- Bauer disk diffusion method. Results: Out of 642 urine samples, 308 (48%) were found to exhibit significant bacteriuria. Females had a higher rate of UTI (68%) than males (32%), with a higher prevalence in the middle-aged group, while males reported a higher prevalence in the elderly group, which was statistically significant. The most common organism was Escherichia coli (57.2%), followed by Klebsiella pneumoniae (26.3%), Pseudomonas aeruginosa (8.4%), Proteus spp. (3.6%), Enterococcus spp. (2.6%), and Staphylococcus aureus (1.9%). UTI were more common in middle-aged female patients (31 to 45 years), while in males, high prevalence was seen in older patients (>45 years). Meropenem, Gentamicin, Nitrofurantoin, and Co-Trimoxazole were amongst the most sensitive drugs against E.coli and K.pneumoniae. Conclusion:Due to the irrational and injudicious use of antibiotics, commonly isolated uropathogens have a changing resistance pattern, resulting in reduced treatment effectiveness. This could be overcome by routine antimicrobial resistance surveillance, antimicrobial stewardship measures, and culture-guided therapy.
