Benchmarking a fast and simple on-site detection assay for the oak wilt pathogen Bretziella fagacearum
Bibliographic record
Abstract
Oak wilt is a vascular disease of oak trees caused by the fungus Bretziella fagacearum . Once infected, trees may die in a few weeks. Although the disease is currently only found in the United States, it has been reported within just a few hundred meters of the Canada–USA border. To limit the establishment and spread of oak wilt in Canada, the development of an on-site, quick and reliable method to detect B. fagacearum is critical. In this study, we developed and validated a new qPCR TaqMan ® assay that can detect B. fagacearum in a laboratory setting with great specificity and sensitivity. Using this test as a reference, we also developed and validated a new DETECTR assay that can detect B. fagacearum under 1 h from a variety of environmental samples, such as mycelium mats and insect vectors, using minimal laboratory equipment. While there are still some limitations to the sensitivity of this assay, we believe that its ease of use, flexibility and accuracy will provide an essential tool in efforts to reduce the spread of oak wilt.

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.
