Abstract
Neutrophils play a key role in the control of Burkholderia pseudomallei, the pathogen that causes melioidosis. Here, we show that survival of intracellular B. pseudomallei was significantly increased in the presence of 3-methyladenine or lysosomal cathepsin inhibitors. The LC3-flux was increased in B. pseudomallei-infected neutrophils. Concordant with this result, confocal microscopy analyses using anti-LC3 antibodies revealed that B. pseudomallei-containing phagosomes partially overlapped with LC3-positive signal at 3 and 6 h postinfection. Electron microscopic analyses of B. pseudomallei-infected neutrophils at 3 h revealed B. pseudomallei-containing phagosomes that occasionally fused with phagophores or autophagosomes. Following infection with a B. pseudomallei mutant lacking the Burkholderia secretion apparatus Bsa Type III secretion system, neither this characteristic structure nor bacterial escape into the cytosol were observed. These findings indicate that human neutrophils are able to recruit autophagic machinery adjacent to B. pseudomallei-containing phagosomes in a Type III secretion system-dependent manner.

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
