Artificial Intelligence achieves >90% accuracy in predicting antimicrobial resistance, accelerates peptide discovery, and improves clinical decision support.
Background
Antimicrobial resistance (AMR) represents a critical global health crisis, driving increased mortality, treatment failure, and significant economic burden. Traditional methods for detecting resistance, diagnosing infections, and discovering new antimicrobials are often slow, inefficient, or lack the precision needed to combat the escalating threat. Artificial intelligence offers a transformative potential to address these gaps by enhancing the speed and accuracy of detection, improving diagnostic capabilities, and accelerating the discovery of novel therapeutic agents.
Study Design
This narrative review synthesizes recent advances in AI-based approaches specifically applied to AMR prediction, antimicrobial discovery, and clinical decision support. The authors drew on representative peer-reviewed studies published between January 1, 2015, and April 24, 2026. The review evaluated the performance of various AI models, including Deeparg-LS, XGBoost, and vision transformers, utilizing genomic, spectroscopic, and clinical data to assess their impact on predictive accuracy, antibiotic prescribing, and success rates in generating novel antimicrobial compounds.
Results
AI models demonstrated remarkable predictive accuracy for AMR, achieving AUC > 0.90 and sensitivity/specificity >95% when analyzing genomic, spectroscopic, and clinical data. AI-driven clinical decision support systems significantly reduced antibiotic mismatches by up to 67%, thereby enhancing therapeutic precision and optimizing patient outcomes. Generative algorithms accelerated the discovery of novel antimicrobial peptides, showing a 76% validation success rate for newly proposed candidates. Deep learning frameworks improved metagenomic resistance profiling, offering more comprehensive insights into resistance mechanisms. Furthermore, microscopy-based diagnostics shortened antimicrobial susceptibility testing (AST) turnaround times by 50-70%, enabling faster and more informed treatment decisions. > Overall, AI stands as a pivotal enabler in the fight against AMR, with substantial improvements across diagnostics, prediction, and drug discovery.
