Detection of multiple strains of rabies virus RNA using primers designed to target Mexican vampire bat variants
Bibliographic record
Abstract
A reverse transcription-polymerase chain reaction (RT-PCR), that uses primers specifically designed to amplify a portion of the N gene of vampire bat strains of rabies that circulate in Mexico, but also recognizing most of the rabies variants circulating in endemic areas, was established. This standardized PCR assay was able to detect viral RNA in tenfold serial dilutions up to a 10(7) dilution using stock virus at an original titre of 10(7.5) LD50. The assay was highly specific for rabies virus. Forty different rabies isolates recovered from different species and geographical regions in the country were diagnosed as positive and negative by the fluorescent antibody test (FAT). These same samples were re-examined by both PCR and the mouse inoculation test (MIT). Compared with MIT the PCR exhibited an epidemiological sensitivity of 86% and a specificity of 91% while its positive predictive value was 96%.

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.
