Occurrence of Cryptosporidium and Helminthosis in Santa Ines Sheep under Dry and Rainy Season
Bibliographic record
Abstract
Cryptosporidiosis is a parasitic disease caused by a protozoan from the genus Cryptosporidium with cosmopolitan distribution and zoonotic potential. The objective of this work was to determine the occurrence of Cryptosporidium and helminthosis in Santa Ines sheep herd during dry and rainy season. This work was developed at the sheep’s breeding sector from the Federal University of Piaui, located in Southern Piauí, Brazil. Fifty sheep kept in a semi-intensive system were used in the experiment using the method according Ritchie, Ziehl-Neelsen and Gordon and Whitlock. Cryptosporidium oocysts were detected in 36% of the animals tested, with 20 males exhibiting a percentage of 50% (10 animals) protozoan in the feces and 50% (10 animals) exhibiting negative results. Among the 30 tested females, 8 (26.6%) were positive and 22 (73.4%) were negative. Concerning the age, 24 animals (48%) were of 0-12 months old, with prevalence of 11 (46%) positive animals showing protozoan in the feces, and 26 animals (52%) between 13-48 months old. The rainy season showed the highest counting of eggs per gram of feces (EPG), reaching a mean value of 2250 thus, a high occurrence of Cryptosporidium was evidenced, with a higher infection degree in young male sheep, predominantly during the rainy season, when a higher EPG was observed.

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.
