The African Swine Fever Isolate ASFV-Kenya-1033-IX is highly virulent and stable after growth in the wild boar cell line WSL
Bibliographic record
Abstract
Abstract In this study, we describe an African swine fever genotype IX virus (ASFV-Kenya-1033-IX), which was isolated from a domestic pig in Western Kenya during a reported outbreak, including efficiency of virus replication, in vivo virulence, and genome stability in pulmonary alveolar macrophages (PAM) and in a wild boar cell line (WSL). The ASFV-Kenya-1033-IX stock, which underwent multiple passages in WSL (more than 20), retained its ability to replicate in primary macrophages and it also retained the virulence in vivo . At the genomic level, only a few single nucleotide differences were observed between the macrophage and WSL-grown virus. Thus, we propose that the WSL cell line is suitable to produce live attenuated ASFV vaccine candidates based on this isolate and probably of similar viruses. The genome sequences for ASFV-Kenya-1033-IX grown in macrophages and in WSL cells was submitted to GenBank and a challenge model based on this isolate was set up, which will aid the development of vaccines against genotype IX ASFV circulating in Eastern and Central Africa.

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.
