A recent Escherichia coli O104:H4 Outbreak in Germany
Bibliographic record
Abstract
The outbreak of Escherichia coli in Germany and in other countries in Europe, including the USA and Canada, in May and June 2011, was apparently the biggest outbreak of food-borne infection. Several thousands of cases have been reported with a high number of deaths. The causative pathogenic organism is enterohemorrhagic E. coli (EHEC) O104:H4. Raw bean sprouts grown in northern Germany were likely the reservoir of the pathogens. Genetic study has revealed an interesting information that the pathogen is a strain of enteroaggregative E. coli (EAEC) with an acquisition of Shiga toxin-encoding gene. Such toxin gene normally occurred in strains of EHEC. The presence of Shiga toxin could cause the hemolytic uremic syndrome (HUS) leading to the fatal complication among EHEC-infected patients. Worthy of note is that in the current episode of outbreak showed numbers of patients with HUS and fatal ity much higher than in previous EHEC outbreaks. Therefore, further investigation is mandatory to conduct on its outbreak in order to obtain more information.

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.
