Study on the Diversity of Serovars and OmpP5 Genotypes of Haemophilus parasuis Isolated from the Same Pig Farm
Bibliographic record
Abstract
Haemophilus parasuis had complicated diversities of serovars and genotypes.In this study,the H.parasuis isolated from the same farm were investigated the serovars by indirect hemagglutination test,and the outer membrane protein P5 genes were cloned,sequenced and analyzed with the neighbor-joining dendrogram from some strains.The results showed that the 42 H.parasuis strains were isolated and identified from the 21 diseased or died pigs.The serotyping results showed that there were 17 of serovar 5(17/42,40.7%),12 of serovar 14(12/42,28.5%),1 of serovar 4(1/42,2.3%) and non-typable(12/42,28.5%).Interestingly,we found that two different serovars simultaneously isolated in the same pig.Based on the difference of ompP5 gene sequences,the five different sequence types(STs,A to E) were identified from 21 isolates,in which STA was the predominant type in isolates.Furthermore,we also found that the isolates of the same serovar had different ompP5 STs,and even the isolates from the same pig also had different serovars and ompP5 STs.The above results exhibited that the serovar and genotype of H.parasuis isolated from the same pig farm possessed the obvious diversity,and serovars and genotypes infected the same pig also existed the diversities.Hence,this study further revealed the infectious complication of H.parasuis in pig farm,and provided valuable information for the study of infection and epidemiology in H.parasuis.

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.
