| Summary: | Background
Urinary tract infections (UTIs) are among the most common bacterial infections affecting people of all ages. The increasing prevalence of antimicrobial resistance among uropathogens presents a major clinical challenge, particularly in empirical treatment. This study aimed to identify the prevalence of uropathogens and evaluate their antibiotic susceptibility patterns in a tertiary care setting.
Methods
A cross-sectional study was conducted at a government tertiary care hospital in Guntur district, Andhra Pradesh, India. A total of 100 urine samples from patients suspected of UTIs were collected and cultured using standard microbiological techniques. Isolated bacterial pathogens were identified, and their antibiotic susceptibility profiles were determined using the Kirby-Bauer disk diffusion method. Data were recorded and analyzed using Microsoft Excel, and results were expressed in percentages and graphically represented.
Results
Out of 100 urine samples analyzed, 34% showed significant bacteriuria. Among the 34 positive isolates, 91.2% (31/34) were Gram-negative bacteria. Escherichia coli was the most prevalent uropathogen, accounting for 48.4% (15/31) of Gram-negative isolates, followed by Klebsiella species at 22.6% (7/31). Antibiotic susceptibility testing revealed the highest sensitivity to Nitrofurantoin (79.4%, 27/34), followed by Carbapenems (64.7%, 22/34). Resistance was notably high against commonly used antibiotics such as Ampicillin and third-generation Cephalosporins.
Conclusion
The findings underscore the dominance of Gram-negative bacteria, particularly E. coli, in UTIs and the growing resistance to frequently prescribed antibiotics. Nitrofurantoin and Carbapenems demonstrated relatively high effectiveness against the isolated strains, suggesting their continued role in empirical therapy. Regular surveillance and antibiogram development are essential to guide appropriate antibiotic use and combat rising antimicrobial resistance.
Recommendations
Promote local antibiogram usage, restrict empirical antibiotic misuse, encourage stewardship programs, update treatment guidelines periodically, and educate healthcare professionals continuously. |
