<i>Salmonella enterica</i> Serotype Urbana Interference with Brucellosis Serology
Bibliographic record
Abstract
Sheep were immunized with killed Salmonella enterica serotype Urbana cells and their sera were tested in various serological tests for antibody to Brucella sp., Yersinia enterocolitica O:9 and Escherichia coli O:157 H:7. Of the eight sheep, all gave a positive agglutination reaction in the brucellosis buffered antigen plate agglutination test (BPAT), seven gave positive brucellosis standard tube agglutination test (TAT) and complement fixation test (CFT) results and four gave slightly positive reactions in a competitive enzyme immunoassay (CELISA). Seven sera were negative in an indirect enzyme immunoassay (IELISA-SLPS) using B. abortus smooth lipopolysaccharide (SLPS) antigen and all were negative in a fluorescence polarization assay (FPA-OPS) using B. abortus O-polysaccharide antigen. Two sheep gave a slight positive reaction in an IELISA using Brucella rough lipopolysaccharide antigen (IELISA-RLPS) and four sheep were slightly positive in an FPA using Brucella LPS core antigen (FPA-CORE). All sheep had high antibody responses to S. enterica serotype Urbana, Y. and E. coli O:157 and 7 were positive for antibody to Y. enterocolitica O:9 when tested by IELISA. The sheep were negative when tested in the FPA using OPS from Y. enterocolitica O:9 but all were strongly positive in the FPA using OPS from E. coli O:157 while seven sheep had titers to S. enterica serotype Urbana. The impact on diagnostic serology for brucellosis is discussed.

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.
