Abstract

fetched live from OpenAlex

Antimicrobial resistance is a rapidly escalating global health concern, largely driven by the overuse and misuse of antibiotics in agriculture and clinical settings. There is an urgent and currently unmet need for effective therapeutics against multi-drug resistant (MDR) pathogens. Antimicrobial peptides (AMPs) are a diverse class of cationic peptides that have the potential to overcome extant resistance mechanisms. We evaluated the antimicrobial efficacy of 13 structurally distinct antimicrobial peptides against a panel of drug-resistant Escherichia coli strains. Toxicity assays, including hemolysis and cell viability tests, were performed to determine therapeutic indices and assess the clinical potential of those select peptides. Our findings indicate that, relative to susceptible reference strains, the tested AMPs retain robust bioactivity against known MDR isolates, exhibiting only marginal or no decrease in antimicrobial efficacy. Among them, TeRu4 emerged as the lead candidate, with a minimum inhibitory concentration of 0.5 μg/mL and a therapeutic index exceeding 256. This study underscores the potential of AMPs to act as powerful alternatives to traditional antibiotics, offering new possibilities to address public health concerns surrounding drug-resistant bacterial infections.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
