Detection of equine infectious anemia viral genome in equids serum samples in Canada
Bibliographic record
Abstract
Serum is a suboptimal matrix for detecting Equine Infectious Anemia virus (EIAV) compared to whole blood (WB), which contains mononuclear cells where the virus primarily resides. WB and spleen samples are generally more reliable for detecting the viral genome. However, at the Canadian Food Inspection Agency (CFIA), only archived serum samples are available for future genotyping efforts. Given this limitation, the present study evaluated the feasibility of detecting EIAV RNA in archived serum samples from equids previously confirmed as seropositive for EIAV using reverse transcription real-time PCR (RT-qPCR). EIAV RNA was detected in of the majority of samples (n= 56, 72.7%), establishing proof-of-concept that the virus can be identified in serum, the only sample type available at CFIA. These findings suggest that further methodological development may enhance detection sensitivity from this matrix. Furthermore, the study highlights the potential for archived sera to support future genotyping projects and improve understanding of circulating EIAV strains in Canada.

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.
