Enteroaggregative Escherichia coli Heat-Stable Enterotoxin 1 (EAST1): A New Toxin with an Old Twist
Bibliographic record
Abstract
Enteroaggregative Escherichia coli heat-stable enterotoxin 1 (EAST1) is a small protein that was first detected more than a decade ago in an enteroaggregative E. coli (EAEC) strain isolated from the stools of a diarrheic child. The EAST1 gene, astA, is not solely present in EAEC, but also in other categories of diarrheagenic E. coli. Strains expressing EAST1 have been shown to induce diarrhea principally in humans, although they have also been associated with piglets and calves. EAST1 toxin has been proposed as a virulence factor implicated in the mechanism of pathogenesis of EAEC and could play a role in the pathogenicity of other enteropathogens as well. This toxin is often compared to E. coli STa enterotoxin because they share some physical and mechanistic similarities. This review summarizes the various observations on EAST1 since its discovery.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
