Abstract
<h3>Abstract</h3> Urinary tract infections (UTI) affect half of all women at least once during their lifetime. The rise in extended-spectrum beta-lactamase-producing strains and potential for carbapenem resistance within uropathogenic <i>Escherichia coli</i> (UPEC), the most common causative agent of UTIs, creates an urgent need for vaccine development. Intranasal immunization of mice with UPEC outer membrane iron receptors, FyuA, Hma, IreA, or IutA, conjugated to cholera toxin, provides protection in the bladder or kidneys when challenged with UPEC CFT073 or 536. Based on these data, we sought to optimize the vaccination route (intramuscular, intranasal, or subcutaneous) in combination with adjuvants suitable for human use including alum, monophosphoryl lipid A (MPLA), unmethylated CpG synthetic oligodeoxynucleotides (CpG), polyinosinic:polycytodylic acid (polyIC), and mutated heat-labile <i>E. coli</i> enterotoxin (dmLT). Mice intranasally vaccinated with dmLT-IutA or dmLT-Hma displayed a significant reduction in bladder colonization (86-fold and 32-fold, respectively) with 40–42% of mice having no detectable colony forming units (CFU). Intranasal vaccination of mice with CpG-IutA and polyIC-IutA significantly reduced kidney colonization (131-fold) and urine CFU (22-fold), respectively. dmLT generated the most consistently robust antibody response in intranasally immunized mice, while MPLA and alum produced greater concentrations of antigen-specific serum IgG with intramuscular immunization. Based on these results, we conclude that intranasal administration of Hma or IutA formulated with dmLT adjuvant provides the greatest protection from UPEC UTI. This study advances our progress toward a vaccine against uncomplicated UTI, which will significantly improve the quality of life for women burdened by recurrent UTI and enable better antibiotic stewardship. <h3>Importance</h3> Urinary tract infections (UTI) are among the most common bacterial infection in humans, affecting half of all women at least once during their lifetimes. The rise in antibiotic resistance and health care costs emphasizes the need to develop a vaccine against the most common UTI pathogen, <i>Escherichia coli.</i> Vaccinating mice intranasally with a detoxified heat-labile enterotoxin and two surface exposed receptors, Hma or IutA, significantly reduced bacterial burden in the bladder. This work highlights progress in the development of a UTI vaccine formulated with adjuvants suitable for human use and antigens that encode outer membrane iron receptors required for infection in the iron-limited urinary tract.

Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
