Persistence of <I>Escherichia coli</I> in Immature House Fly and Stable Fly (Diptera: Muscidae) in Relation to Larval Growth and Survival
Bibliographic record
Abstract
The persistence of Escherichia coli in artificially fed larvae was examined for up to 48 h after ingestion by house flies, Musca domestica L., and stable flies, Stomoxys calcitrans (L.). The rate of change in the E. coli load was similar for both species for up to 5 h after ingestion. Up to 48 h after ingestion, abundance of E. coli declined in immature house flies but remained constant in immature stable flies. When different E. coli concentrations were fed to larvae, the abundance of E. coli increased in stable fly larvae regardless of the initial concentration. The E. coli load in house fly larvae increased when larvae were fed a low concentration of bacteria, but it declined when larvae were fed a high concentration of bacteria. Survival of house fly and stable fly larvae averaged 62 and 25%, respectively, when reared on pure E. coli cultures. These observations suggest that house fly larvae digest E. coli and use it as a food source but stable fly larvae do not.

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.
