Co-culture metabolomics: a powerful tool for uncovering host-pathogen phenotypes driving <i>Burkholderia</i> infections
Bibliographic record
Abstract
ABSTRACT Melioidosis, caused by the soil-dwelling pathogen Burkholderia pseudomallei (Bt), is a severe respiratory infection with limited treatment options. To investigate the host-pathogen metabolic interplay occurring during these intracellular infections, Hicks et al. built upon an in vitro co-culture model they developed with airway epithelial cells and Bt as a surrogate pathogen (D. J. Hicks, N. Aiosa, A. Sinha, O. A. Jaiyesimi, et al., mSystems 10:e00611-25, 2025, https://doi.org/10.1128/msystems.00611-25 ). Using an untargeted metabolomics approach tailored to central metabolism, they identified several host pathways that were altered during the Bt infection: polyamine biosynthesis, nicotinamide adenine dinucleotide salvage, and the tricarboxylic acid cycle. In addition, they found that several bacterial metabolites, including methylated nucleotide bases, peptidoglycan precursors, and amino acid derivatives, were altered due to Bt infection. These results show that co-culture metabolomics is an effective strategy for identifying host-pathogen metabolic phenotypes resulting from bacterial infections and can uncover new therapeutic strategies to combat melioidosis.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
