The RNA virome of human and animal parasitic nematodes
Bibliographic record
Abstract
Abstract Screening published transcriptomes, we have discovered 75 RNA viruses that infect 27 species of parasitic nematodes, responsible for >1.5 billion infections in people and animals. Our analysis shows extensive diversity and a conserved global spread of virus/nematode associations across multiple continents suggesting an ancestral acquisition event and host-virus co-evolution. Characterization of viruses of Brugia malayi (BMRV1) and Onchocerca volvulus (OVRV1) shows that these viruses are abundant in reproductive tissues of adult parasites, suggesting sexual/vertical transmission routes. One striking feature was the presence of BMRV1 RNA in epicuticular inflations in older parasites. BMRV1 and OVRV1 elicit antibody responses from the vertebrate host demonstrating direct exposure to the immune system. The parasites hosting these viruses have an intimate, chronic and life-long exposure to vertebrate tissues creating the opportunity to cross species barriers and so act as a novel paradigm for parasitic nematode diseases and a potential hidden reservoir of emerging viral diseases.
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.
