Abstract
Mycoplasmas, known as the simplest self-replicating organisms, are distinguished phenotypically from other bacteria by their minute size and total lack of cell wall. The poultry industry is affected by several species of mycoplasmas but Mycoplasma gallisepticum (MG) is the most economically significant one. The attachment of mycoplasmas to the host respiratory epithelial cells constitutes a critical step in the pathway leading to infection and disease, and it is achieved by lipoproteins localized on the bacterial surface. GapA and CrmA proteins showed to be critical in this adhesion process, as well as in further disease development. In this work, the molecular cloning of these genes coding for both proteins, as well as their expression, purification and immunogenic response induced by the obtained products, are described. Only a fragment of gapA gene was cloned, while crmA was full lenfht cloned as designed. In both cases, the obtained recombinant proteins were fragmented but this fact did not affect the purification process by the Immobilized Metal Affinity Chromatography (IMAC). At the end of the process, the final products conserved their antigenic properties. These recombinant products could be used for future studies related to the pathogenic mechanisms of this bacterium.

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.
