Adherence of bovine viral diarrhea virus to bovine oocytes and embryos with a hardened zona pellucida cultured in vitro.
Bibliographic record
Abstract
The purpose of this study was to investigate the adherence of bovine viral diarrhea virus (BVDV) to bovine mature, or immature, cumulus-free oocytes and to in vitro fertilized embryos, maintained in vitro in a ligated bovine oviduct to allow for the hardening of the zona pellucida. Incubation of the oocytes and embryos in the oviduct for 5 h caused hardening of the zona pellucida as measured by resistance to pronase digestion (which increased from approximately 3 min to 7 h; P > 0.001). However, there was no difference between the number of infected oocytes and embryos (n = 965 in 193 samples) following experimental exposure to BVDV regardless of whether or not they were previously incubated in the oviduct (P > 0.05). It was concluded that the modification of the proteolytic resistance properties of the zona pellucida during in vitro oviductal incubation did not influence the adherence of BVDV to zona pellucida of oocytes or in vitro fertilized embryos.
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.
