Molecular characterization of extraintestinal pathogenic<i>Escherichia coli</i>(ExPEC) pathogenicity islands in F165-positive<i>E. coli</i>strain from a diseased animal
Bibliographic record
Abstract
Septicemic Escherichia coli 4787 (O115: K-: H51: F165) of porcine origin possess gene clusters related to extraintestinal E. coli fimbrial adhesins. This strain produces two fimbriae: F1651 and F1652. F1651 (Prs-like) belongs to the P fimbrial family, encoded by foo operon and F1652 is a F1C-like encoded by fot operon. Data from this study suggest that these two operons are part of two PAIs. PAI I4787 includes a region of 20 kb, which not only harbors the foo operon but also contains a potential P4 integrase gene and is located within the pheU tRNA gene, at 94 min of the E. coli chromosome. PAI II4787 includes a region of over 35 kb, which harbors the fot operon, iroBCDEN gene clusters, as well as part of microcin M genes and nonfunctional mobility genes. PAI II4787 is found between the proA and yagU at 6 min of the E. coli chromosome.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
