Exploring Aminopenicillin Resistance in Uropathogenic Escherichia Coli and Optimized Lead Prediction to Overcome Resistance Through New Generation Tools
Abstract
Introduction: Urinary tract infections (UTIs) are a prevalent condition caused by bacteria such as Escherichia coli, Klebsiella, Proteus, Staphylococcus, Enterococcus, and Pseudomonas aeruginosa species. According to the Ministry of Health and Population’s 2079/80 annual report, Nepal recorded 5,284 cases of UTI-related morbidity. The growing burden of infectious diseases and antimicrobial resistance poses a significant threat to public health. Method: A retrospective, descriptive cross-sectional study was conducted at a tertiary care hospital in Kathmandu, Nepal, from July 2023 to January 2024. A purposive sampling technique was employed, and the collected data were analyzed using various standard software, web servers, and statistical modules. Results: Out of 3,000 urine samples, 246 exhibited significant bacterial growth. Among the isolates, Escherichia coli, the predominant Gram-negative bacterium (63.4%), demonstrated 88.46% resistance to amoxicillin. Similarly, Staphylococcus aureus, the dominant Gram-positive isolate (6.3%), showed 50% resistance to ampicillin, indicating a rising trend of resistance to aminopenicillins. Conclusion: Amino Penicillin resistance in Escherichia coli species is at high levels, BA-3 and BA-10 emerges as a promising candidate with better physiochemical and pharmacokinetics parameters for future therapeutic development. Experimental validation and exploration of additional resistance mechanisms are recommended for comprehensive treatment…
How strong is the evidence?
Evidence Hub reads this as a cross-sectional. Its evidence level is 4 of 5 (Low · observational). Observational designs can show an association but not prove cause.
